I played on someones Beastie Feastie that was a Pac-Man conversion (it included the PCB, marquee, glass bezel and control panel). Pretty fun game, but I think they're really rare. Like others posted, there are several versions, although they are different (at least The Glob, Super Glob and Beastie Feastie are different). Some get harder quicker than others, the sounds and graphics are a bit different, etc, but they all are pretty much a similar game.
