Always brings a tear to the eye to see a nice collection like that.
Back in the day these keyboards would like lined up and no-one would have given them a second look.
I'm glad someone else like them
. I just like what they represent overall I guess.
In addition to these I also have a Das Keyboard (<rage>...) and I'm thinking of picking up an HHKB (<YeahIGetWhatThatDoesHere>...)as a present to myself for my birthday.
That is indeed ambitious. One look at clickykeyboards.com or the Model M wikipedia entry would dissuade me in a hurry.
The Model M has scarce and pricey variants (eg industrial SSKs and M15s), while there were a lot of weird Fs from the early days that will be just crazy rare.
As with coin collecting, I recommend that you start with a "type set" and collect a good example of each major type, before drilling down into things like part numbers.
I'm only focused on the BS, non-Lexmark, non-industrial, non-security harden, Model M's right now. I think a regular SSK is an achievable goal at present, it's gonna cost a pretty penny though.
Don't get me wrong, I want all of those, but I see them at a different price point and would be a more justifiable purchase when they're completing a substantial collection. As for the Model F's, those are complimentary to the collection I would say. Mostly, I've been buying them from recycling centers, yard sales, and craigs list; ebay inflates stuff quite a bit
