I lost the use of so many keys on my ergo board that I had to resort, again, to the standard one till I could get something ergo again. A friend found an ergo keyboard, sans touchpad, at the Goodwill for $3.00 for me. I need a piece of plywood cut to fit my pulled-out desk drawers so I'll have room for the mouse and then I should be almost as well off as before. For now, this is working and I am very happy not to have to search for b and B's any longer (and numerous other keys).
The flexi-boards look cool.
I'm glad you found a replacement for your ergo board--and at three bucks too! Nice :)
