Scissor switches always bottom out, which is unhealthy:

"Key Travel Distance: Scissor-switch membrane keyswitches are not 'full-travel' and typically have a key travel distance of 1 - 2.5 mm as compared to 2.5 - 4 mm for memrance keyboards. As such, when typing on these keyboards it is almost impossible to prevent 'bottoming"

The ErgoDox seems good, but I don't want to build my own. Afraid I'll screw it up. :-(

That may be, but I feel much less fatigue using scissors than the membrane domes. At least comparing the MS Ergo 4000 vs Sculpt. The new switches on the ThinkPad X series tire me out more than the IBM style, though.

ErgoDox has a fundraiser for a preassembled version. They've raised nearly $100K. [1]. Which is funny because a manufacturer was telling me how expensive it was to make keyboards and so on, that they'd need like $70K. OTOH the ErgoDox isn't really standard; people must be desperate.

ErgoDox moves several keys like Enter to the thumbs. The thumb layout matches the Kinesis Advantage: http://xahlee.info/kbd/i/Kinesis_Contoured_Keyboard_Classic_...

The Kickstarter Model 01 does the same thing with a different layout: http://www.keyboard.io
