I'm personally very excited about the Matias ergo pro : http://matias.ca/ergopro/pc/

Smallish, cut in half, great switches, no staggered columns (I want to stay "compatible" with my laptop keyboard). It looks just like my old kinesis freestyle but of better quality.

I did try an ergodox for a while, but instead of biting the bullet and using for a while I would tweak the keymap to infinity hoping to find more compatible memory muscle to what I already know.
