Hmm. However to explain what I've been up to? I'm not sure there is a particularly compelling story, besides being the natural result of coming to Deskthority!
My first mech was an IBM Model F XT. That set a high bar, and the core of my boards are still IBM. Got everything from beam spring, Model F and Model M now, in compact form factors throughout the range, as much as 3276s count. In fact, I'm pretty much done for IBMs, as far as I can tell. Never say never (I still have zero industrials) but I might as well thin out a few before considering any more.
What I was originally up to was exploring switches. In fact the first mech components in my home were all in Mr. Interface's switch sampler. Those pointed me to IBM and Topre (along with respected opinions I found here) and to keep an eye on damped Alps and those crazy Futabas. I still haven't got a Futaba board, but damped Alps came my way when I picked up an AEK II (the original board whose vastly outsized reputation in Apple circles
caught my interest in this realm) and I must admit a fondness for Montereys over any clicky MX.
Something I had figured out from the get go was that smaller keyboards are my thing. From my Kishsaver and SSKs to my (coming) HHKB and everything else, a TKL is a big keyboard in my view and a 60% is ideal. The little guys are much easier for me to work with, as well as store of course. And they get the lion's share of my all important metric: actual use. I'm not really a collector so much as I am a user of these boards. Although once you've more keyboards than fingers, this gets a little difficult to argue!
Custom building is the other axis for me. My first MX board was one I built myself (with immense help from Matteo) and several of my acquisitions have been for new projects. I've got something in mind for Mitsumi Miniature switches, and Cherry M84s, both of which are crucially MX mount compatible. My caps collection makes that a big deal indeed. 7bit's and Matteo's custom friendly creations are a dream for the kind of layouts I want to make, instead of having to watch eBay for the long haul, hunting obscure Alps mount boards.
Speaking of eBay, by my count I've only ever bought 4 keyboards there. I got three boxes from Cindy with that many! I'm lazy when it comes to hunting, see. DT's much more my place than scouring any storefront.
