Restoring pinball machines

Pinball board are really hard to find, to be quite honest, I'd look on eBay first of all, if nothing turns up there, try looking at Steve Young's pinball page www.pbresource.com. He specializes in Gottlieb parts and supplies. If you come across a non-working board, check out www.coinopcauldron.com, they do board repairs at a fixed rate. Great people there!
