If you don't mind doing a little CAD work, there's a couple places
that do inexpensive single sided boards, like olimex or futurelec.
It's also not that hard to etch your own single sided boards.
Depending on the micro, you might be able to buy a proto board for
that specific micro, which ...Re: great pcb design software
