I visited Pinballz on Research Boulevard a couple days ago. Very nice collection of pins. I like going to a place like Pinballz (or PHOF, or PAGG, or whatever) and coming out of there with a modified wish-list in my head (that mental list, in the back of my head, of games I might want to own someday). So, this time, based on fun factor, Monopoly stayed on my wish list. I don't know why I like it as it isn't a very highly rated game. I play it every chance I get trying to figure that out! Scared Stiff moved higher. Black Rose moved lower.
As others have noted, quite a few games had problems. One had a stuck UR flipper, a few had switch problems. If I owned a place like Pinballz, I'd probably go nuts trying to keep every pin in tip top shape all the time.
