to clarify: protos were $25 each (which is still less than sparkfun, since one of these == 2 of theirs) talking to SmashTV, it sounds like we can get a small run done for under $15 per brd (about half sparkfun price) with ENIG so contacts should be fine without extra effort required. so for example, to make an 8x8 monome like thing (i think i'll call mine "the thing" since that's what SmashTV has been calling it and he's my guru *whack*), you would need two of these brds and 4 button pads from sparkfun. it might be a good idea to combine a bulk order of button pads with the brds. note that this is not a project for beginners, but it was my first SMD work and wasn't too hard. and way easier than it would have been to wire all the dins and douts on other brds. the second brd went quite quickly since i already had the hang of it. people with steadier hands than mine should have no trouble at all. since you must solder chips directly to brd without sockets, an ESD safe soldering iron is highly recommended.
