This will be a freeware product, An SMD PCB isn't that easy to make as a hobbyist. If the board size is tolerable (eurocard 10x16cm or under) it won't cost that much to make professionally. But of course, that is only in relative terms. Expect starting fees of 1000-1500 FIM and a price of 20-30 FIM per PCB when produced in batches of 50-100 pcs. Not too expensive but someone will still have to pay for it. (FIM to Euro: divide by 5.94573; FIM to USD varies but right now divide by 6.732.) Of course there are bigger proto-PCB houses around the globe, like at http://www.4pcb.com/ and others, in Finland there's http://www.saunalahti.fi/~criadix/ and in Estonia places like http://www.kamitra.ee/ and so on.

If someone knows a cheap place for doing this (I The chips will be pretty easy to solder in, unless there are BGA chips on the board (in that case - forget it!) I've soldered many 0.63mm-pitch chips with an ordinary fine-tipped 50W soldering iron and fine solder, and solder wick for the occasional mistakes. - This message was sent through the cbm-hackers mailing list.
