So my current keyboard for work is starting to hurt my hands.
This is my first space invaders board (got it second hand at a thrift shop and cleaned it up carefully).
I'd get you the model number but it is at work...
My hands are hurting badly as I type a lot. Tingling in the fingers and slight numbness.
The switches actually seem to only depress at very strict angles which is unnatural for me.
The way I push them they actually feel more ridged that my Model M's.
I use an Adesso at home with MX Blue keys in it and never have pain.
I'm also a big fan of IBM Model M having 2 by IBM, one by Lexmark and one by AT&T (search it on the forum confused the hell out of most people).
Barring case design, I'm looking for something quietly clicky or atleast very tactile for work in the 30 dollar range used.
I also have a taste for exotic things too so strange layouts are cool (love the extra keys on the squarish looking POS boards)
I've seen this keyboard which looks like it might be mechanical as it is IBM but I can't be sure...
