Hi there, I must have been lurking here for a long while now.
I usually type on Kinesis Advantage 2 (own like 3 of them), but also have:
Ergodox EZ
Dactyl Ergodox
Keyboardio Model 1.
In the past, I had Ergodox (Falbatech version, circa 2015), Ergodox Infinity, Atreus, Planck, Atomic and a few more - All of the above hand soldered.
I feel like I'm set on sculpted keyboards, can't really use flat layout like Ergodox - too much reach required.
My next project is to put to gather a Dactyl Manuform and see how it works, might even do an ordinary version and also manuform with trackball...
