I have a lot of keyboards, but the ones I use most are:
- Unicomp Ultra Classic
- Pretty much stock black Filco with MX Browns
- Stock Realforce 104 UWS, which I actually use the most, but I wish I could get blank modifiers for it, sadly the ones for HHKB don't match colour
I also keep to remind me why I don't need them (so I don't buy more keyboards like that):
- Black HHKB Pro Silent
- GH60 with PCB mounted 62G Zealios and Silencios in HHKB layout (which I use when traveling actually, it works with iPad, while HHKB doesn't)
- V60 with silent Matias
- ErgoDox with 62G vintage blacks (I actually use it sometimes, so it's not useless)
- Filcos of different age and layout (fullsize and tenkeyless) with MX Blues, Browns and Reds, one tenkeyless with MX Reds is enclosed in alu case and sports GMK black double shots, which I regret buying - apart from nicer profile and being thicker, they're not better than super cheap Tai Hao caps, which actually work better with Costar stabs
- Couple of standard and terminal Model Ms (which I actually use to play retro games on my IBM 486)
- Couple of XT, AT and Terminal Model Fs, with one AT Model F USB Modded internally using Soarer's firmware with teensy
- Plenty of retro boards with Alps (and clones), Cherries (and clones), Space Invaders, Acers and what not - basically keep them in basement for future generations
