I was wondering if anyone used the ergodex. http://www.ergodex.com/content12.php

I've got an old Nostromo N50 and the Razer Tarantula keyboard but they're not really cutting it. I was looking at the Xkeys which everyone seems to love.

The Xkeys pro is going to run me around $170 but the Ergodex is only $140.

Does anyone have any experience with the movable key system?
