Just spent an enjoyable 45 minutes or so reading through this thread and felt the need to contribute the pinball hall of fame here in vegas. 100's of machines all in pristine working order. They have twilight zone, attack from mars, and many rare and old games(including one with a weird vertical playfield where you have to shoot the ball up a series of ramps to the top of the machine). They claim it is one of only two in existence. So if you are a fan of pinball machines and here in vegas do yourself a favor and check it out. You won't be sorry.
