Sadly, I'm in the UK, so buying from America means a hefty post cost, and a 20% import fee.
Hi, so, I'm thinking of buying a keyboard that I won't feel guilty about throwing it in the bag and take it around with me and thought a Model M would be perfect for this. But, I just don't subscribe to the prices they are sold for on Ebay - just because a bunch of geeks will pay that price doesn't actually mean they're worth it, right? After all they're 20+ years old, they're going to need work on them sooner or later. In England, we don't have Thrift stores, and computer keyboards are not the mainstay of charity stores, so where could I get a sensibly-priced one from without the geek premium??$60 or 40£ is not a bad price for a good keyboard that could outlast you and seems the going rate. You couldn't make a Model M for that price today, particularly with the same quality in it. They are fantastic boards that have outlasted anything else on computers and command a decent price, calling it a geek tax is sort of bs, as they were very expensive when new. Personally, I think the Model M is a massive keyboard and you won't find an F model or SSK for anywhere near a decent price (being how rare they are), and even then you still have the massive wight and size (for being a "compact").
It is more like £40 = $60.Oops, i got that backwards, fixed
Thanks, but I don't even want to have to pay £40+ for a keyboard I would have to do work on;dismantle and clean and add nuts and bolts!I don't know of that would make it hard for you to find a model m.
I recently got some quotes for Model M's in the UK, the usual price is £100 for generally C grade stock. Given eBay prices £40-£45 is very good. I'd be very interested to see if you find one any cheaper.

Don't you have anything better to do with your life than yammering away on the minute details of a keyboard? I have both an M and an F that I picked up at goodwill for nothing 15 years ago and for the first time yesterday I googled about them and found 'enthusiast' (here an euphemism for retarded) websites where idiots bounce off the walls telling each other about the orgasms per second they have when using them. And 'using' is an overstatement with 90% of those morons. Most are busy opening them, cleaning the last atom of dirt off them, 'restoring' what doesn't need any restoration, 'upgrading', thinking of names for them, 'modding', taking photos, showing them off, in general jerking off about the clicky sensations and the superb accuracy of their typing and other general uber-dorkiness. What I never found there was anything useful to do with them, ie. actually program a computer.
Go type 'messenger lectures' in youtube and see what smart people look like, then kill yourself disassembling your One True Keyboard(TM) for the nth time and swallowing all the buckling springs.
And then mail one of your remaining model Fs to me.

Thanks, but I don't even want to have to pay £40+ for a keyboard I would have to do work on;dismantle and clean and add nuts and bolts!I'd say it's a fair price, but your choice of course. If you're trying to find a cleaned, bolt-modded M for £40 you might be looking for quite a while though :P .
Taobao is a site on which a '85 model M in decent condition could be had for $65, and a less antiquated one for $40. But of course you pay another $35 in shipping to Canada, so it's not for everyone. For the same total price you could get more keyboard and less shipping if you get a nice deal on eBay. Deals abound on Taobao, if you could overcome the stupid search algorithm that literally finds no matches for "Model M".
I also found an F107 listed for $50, but it was sold the day before I could buy it.
If you can figure out where the local e-waste recyclers are, I'd check that out. I've picked Model Ms for $2 a piece.

I'd pay <= £10 for a dirty keyboard in need of cleaning, nuts+bolts and needs the connector sorting because it's currently useless as a PC keyboard.

I try to re-post it a couple of times a year, so that it is not forgotten.
I for one appreciate it, comedy gold.
40 pounds for a mechanical keyboard is cheap, especially given that these ones can easily last over 30 years and most mx clones that price wont make 10.Wow, ok, so buy them all and resell them. You'll easily make lots of moolah if they're so cheap. If you're right and they last over 30 years, then that means they have... about 3 more years to go then before they all crap out.
No one is going to see you a cheap m because they feel sorry you dont want a "geek tax" aka supply and demand is happening.Not so much supply and demand, but just marketing and people cashing in on that. It doesn't make them worth what they're being sold for. Just because one or two fools who views it will pay the premium doesn't mean anyone else will.
Mechanical keyboards cost money because they are a dream to type on and they last decades if you take care of them."A dream". Steve Jobs would be proud right there. That's the evidence of you believing the hype. They're a type of keyboard only.
They're a type of keyboard only.
Someone uses the "troll" word and you're influenced enough to cry troll. If I wanted to troll, I could easily troll lots of people here. But I haven't. Model M prices have come down drastically in the last few years - why? Marketing / fad wears off. They're still over-priced, regardless of whether you agree with me or not.Something is worth exactly what people are willing to pay for it. People pay more than you want to for Model Ms, so you want to pay less than what it's worth. As such, unless you buy one from someone who has no idea what they're worth, or you find one in a skip, you probably won't find one for what you're willing to pay. Simple.
They're still over-priced, regardless of whether you agree with me or not.Good. You have to be the most confusing user here! By who's standards are you talking by the way? Yours?

Who is actively marketing Model M's?

Personally, I have always thought that good common vintage M prices should be in approximate parity with new Unicomp prices.
... Blah blah troll blah blah I'm soo cool and beautiful blah blah But, I'm annoyed with you for some reason blah blah......You don't know what marketing is.

And you are trying to imply you know more about marketing than me! How are Apple able to sell such way overpriced items? Oh that's right, the mindblowingly amazing marketing they did in the 90s. Yep, the 'm' word. But, you knew that already, right? The truth is, there is no "dream". Only to make people think there is. By making people believe something is elusive and how they can join the 'cool club' if they own a certain product is what pushes prices up. Apple nailed that perfectly. The actual quality has nothing to do with it because history shows quality doesn't actually matter when it comes to sales or price.

Partly agree, but with a new Unicomp at least you can plug it in and go. You can't with a Model M, and the price should reflect the work that needs doing to it or the additional cost to get it up and working. By that very nature, the keyboard becomes only a geek keyboard.

"throw it in my bag and take it around..."
Is this a joke?
The vast majority of Ms do not require bolt-modding. Even if you're missing 15 or more I think it's unlikely that any keys will be impacted or dysfunctional. I'm pretty convinced people won't be able to feel the difference between 10 missing bolts and none missing at all for boards in otherwise identical condition.

One 87 with 0 broken rivets, one 87 with about 10-15 broken rivets and I used it for a couple of years that way, one 92 with about 20-30 broken rivets and "NIB" (sealed), and an 89 with no broken rivets. All but the 92 were perfectly usable. I can tell a difference in 87 that I restored, but it's not a huge difference.

The 87 with 10 broken rivets came from a school and was shipped across the country. So was the 89. I think it's just luck of the draw or maybe storage conditions...

That's interesting. My Model M needs a bolt mod BAD. The enter area is so soft it feels almost linear. The sound is completely different. I haven't been able to open mine up fully yet (although I have had it for a long time) so I don't know how many are missing.

I'd be so scared to do it myself on my main board. Not that I couldn't learn, but I just know I'd mess it up unless I bought a couple to practice on first.
My oldest M, a 1390131 from 1986, came to me about 4 years ago with every single rivet intact, but I did a bolt-mod on it anyway because it was a primo specimen and I wanted to "go all the way" with mods.
I got a new-in-box SSK from Cindy's sale a couple of years ago which I considered leaving in the box for resale at a profit, but when I opened it I found that over a third of the rivets were broken, including a majority at one end. It worked, but that side felt terrible.
who knows what causes these things to snap.
That is gold right there.

Everything should be the price he says it should be, and if it isn't, it's priced wrong. Almost as if he was the whole market for them.

Oh no! Have you ever dared to haggle for a different price from a seller? Supplier-led prices only works for certain things. Throw-away things like keyboards are not within those things. The buyer is nearly always in the drivers-seat when it comes to pricing on all goods. Think, there's five people in the world who want to buy something, and a seller just happens to be selling 5 at a ridiculous price. If the buyers refuse to pay, the seller has storage space taken up by deadspace. So, who's going to give out first? Potential buyers can use another alternative keyboard easily, however the seller is relying on selling the items to put food on the table. The seller will always drop their prices. Those that don't are either out to screw you or won't last long.

I don't think that is true. Whenever I am selling, my prices are "firm"
If the item does not sell after x amount of time, I may drop the price myself, but I do not respond to attempts to negotiate.
Buyers love bargins, huh? So... sellers up their price to encourage people like you to make offers and think they got a good bargin. Seller trick #1041.

I always attempt to negotiate a price down. I got 2 SSKs for less than asking price...and I'll bet it's because no one else would even bite because the price was either too high or they thought the seller would not budge on price.

To answer your OP, I can import a fully functional, plug/play Model M for approximately $70 shipped, $60 if in bulk. All this is $CAD. The price of the keyboard itself is low, but the margins when sold on my end aren't high enough for me to make this a routine import. I only stock 5 or so IBM keyboards at maximum, since I don't have a dedicated warehouse for merchandise.
So, if you're still set on getting a Model M, here's what I can do. I'll purchase the keyboard with the assurance that you will pay the full cost to me, and it will be shipped directly from source to you, so I don't have to cover shipping from my locale to Britain, the shipping cost being the main stumbling block whenever I make a sale. I imagine that this cannot cost more than £50 when it reaches you, and £50 would be, according to what appears from your posts, a reasonably price for a functional Model M in good condition. 1390131 and 1390120 are out of the question, though.

WHO ARE YOU to have this opinion? By the way, if you feel they aren't worth the money, take my advice....
Get another hobby and BUY SOMETHING ELSE.
50 pounds sterling is quite cheap for a Model M, considering how they retain functionality and only a third of their original price.@QuincyJones

Really the only reason im bolting is is because it was so effing dirty, I just wanted to get the parts apart and clean the hell out of it.
Hmm that is a very valid reason to bolt mod it. Thankfully my unicomp was new so I didnt need to mod anything yet.

This is not my only reason but if I am serious about one, I want to know that every part of it is squeaky clean and germ-free.
ZOMG! i WANT TO BOLT-MOD TOO!!!1 CAN I HAZ COOL? BOLT MOD. SUCH KEYBOARD GEEK. I WANT TO BOLT MOD. MUCH HACK. LOOK AT ME EVERYONE. I'M BOLT MODD WIZ. STRANGERS GIVE ME YOUR APPROVAL. MUCH WOW.
This is my first M, so I want to be sure before close the deal.
The deal was closed when you received it.
If you bought it from Ebay, take out all the keys, keep them and send it back complaining to Ebay not as described. Buy another keyboard, and then take out the keys and send back the keys in an envelope stating that's all you received. Job done. Ebay gives you a free keyboard. You're welcome.

Do model f's need the bolt mod too though or is that M only?
Model F is completely different from Model M, the only parts that interchange are the key caps and stems.
Fs can be dis-assembled and re-assembled non-destructively, and can be "bolt-modded" although it is a very different sort of operation that is completely optional rather than mandatory after cracking them open. The "barrel frame" of the M, which is the component that the rivets are part of, does not even exist in a Model F.

I was wondering, if a Model M could be clamped together instead of being bolted? Like held together with some strong clips.
