I answered a CL ad for a Williams IJ and went to check it out this afternoon.
IJ was fun, nice condition, extras, good price.
He also had some Sterns I had not played before.
TSPP was fun. I would definately need to learn the rules better.
Spiderman was really fun. The third flipper to hit Venom, Doc Oc is neat, the motorized Sandman targets, and the shaker motor made for a cool game.
Iron Man was awesome. It is fast! The playfield was pretty clear, not crowded. The Iron Monger was cool with the magnet that throws the ball around. It reminds me of the safe on Sopranos, minus the magnet, and I like that safe target. The kicker shoots the ball towards the flippers very fast. The playfield seemed bright, easy to see the ball pretty much anywhere.
I liked all three Sterns, and would like to own any one of them, but Iron Man took the cake.
