I may have a lead on a reasonably priced Bride of Pinbot. Are there any common issues I need to watch out for on these machines? What should I check? For example, I have seen pictures of several machines and some seem to have a yellowing playfield, is this camera trickery or can this happen to a BOP? And of course, what are the other common issues with this game?
