I'm not sure if you mean stripboard or some other type of prototyping board, but RP Electronics has pretty good prices on prototyping PCBs. I bought a few of their 8"x15.5" stripboards (p/n R67-1902F) for $27/ea for my sequencer project. http://www.rpelectronics.com/English/Content/Divisions/Div_88_140.asp -Dan Gendreau
