I'd be more interested in a group buy on some LMD18245T chips, as they
will do bipolar instead of unipolar motors. I had a board made and
software nearly finished using a PIC18F252, but am now in the process of
porting it over an AVR mega48. All in the interst of saving $3.50 per
microcontroller. Plus an excuse to learn AVR's...
