Yep JD not too many of these survived that grinder. I count 6 factory-customized Industrial SSK's with the blue keys in the hands of collectors, plus the few I sold in the past 12 months. Of course there are a number of "regular" Industrial SSKs out there as well.
A warning - this post explains why a keyboard is rare - skip it if you don't like such posts
If you think it's a regular thing that these custom-blue keys Industrial SSK's come up and that the price will go lower and lower, it is only because of my lucky find of a batch of them is making them come up a lot more than they have in the past 5-10 years. That's coming to an end sooner than you'd think
Besides my BIN listings, only two have sold at auction this year and last year combined. Yes one sold for $100 or $200 less than my $900 off-eBay discounted price for all forum members, though it needed a few hours of clean up to say the least and eBay listed it as local pickup only, though the listing said shipping was an option so that may have discouraged further bidding.
I guess more than one person thought to hold on to them for years after they stopped being useful in their original industrial-type setting. Maybe the rest went through the same grinder that ate up those poor F62s that elecplus tried to save recently? You never know.
And yes I hope that a room full of F77s are found so I can just keep my listed F77 as a backup. There's just so much demand I've seen for it and offers I've received that I've gone and listed a price above the top bid I've been offered (I am open to negotiation on the listed price). If supply increases these may be worth less. But then again not one F62 has been found yet after Tinnie's 2013 batch, so those probably won't be worth less any time soon either.
Based on my Google searches, here are the 6 sellers/owners of these 1395682 custom Industrial SSK keyboards, besides the few units that originally came from me (some GH/DT/Reddit members from the US and abroad have posted keyboards formerly in my collection):
2 - clickykeyboards web site - probably sold years ago
1 - webwit - from Tinnie's find
1 - eBay last year
1 - eBay a week or so ago
1 - eBay in 2010 or 2011, per an old GH post
Plus a few others I'm sure.
I can no longer store my keyboard collection so I began selling them. I apologize I have been more of a lurker these past years than an active participant.
JD and others - The high end of every hobby is expensive and prices are considered extravagant by most - just check eBay for the true price people pay - complaining they overpaid won't change anything. Collectors pay based on supply and demand.
Checking auction listings and past sale news articles:
Monopoly sets have sold for over $5,000
Antique phones sell for hundreds of dollars
Cameras and camera lenses sell for $1k to $2k regularly
Baseball cards have sold for over $1 million
Keyboard caps regularly sell for $100s each in secondary markets
And yes keyboards have sold for $2,000 to $2,500 (a cherry MX5000 and a datahand or some ergonomic model I think)?
I am well within my rights to try to sell part of my keyboard collection at any price I'd like. No one's paying more than what they agreed to pay for anything here - those buying these at my full asking prices know what they are collecting.
