I've gotta say Roller Disco... mainly coz its the best of the three sys1s i own. The only others i'm familiar with are Countdown, Pinball pool, Hulk and Charlies angels. My home made pin project originated from a dead Charlies angels cabinet, and i missed out on owning a Hulk machine not too long ago, that my cousin owned.. he sold it for $350 i think!!!  D'oh!!!

Yes - now I recall your name, Mitch.. That home made pin was an incredible game - If you find the time - I'd love to see it's development from scratch in a thread.
