Great work.
My main moan though would be the additional keys, is it not possible to get the original space bar size and remove all extra keys an an option for the purists? if not wouldn't it be better to have the extra keys next to the space bar so that the A and ALT are in their normal locations? also maybe just drop the caps lock light to allow you to use original size CTRL/CAPS keys? I think the size of those keys being reversed would bug me more than lack of a light.
You can't please everyone I guess and with you funding it yourself I bet it's expensive but more options would be nice if possible.
