Hi! I use KiCAD quite a bit and have designed several
PCBs with it. It
works fine and is completely unrestricted. I think it is a fine product
and
recommend it whole heartedly. It has improved dramatically over the last
couple years. Also, all of the N8VEM PCBs are posted on the wiki in the
KiCAD format.
Andrew, much of the people I know are switching to Kicad. Although I
have access to an (original) license of Altium Designer, I'm thinking about
knowing more about kicad. Hope it replaces eagle! :D
