Well, I bought the game last night. Got it home, and you guys are absolutely correct - This game is Frackin' Awesome! Of course any time you add a pin to your lineup it becomes your favorite pin - at least for a little while.
It turns out the game was being sold by PinballGary. Apparently he uses this board, but not very often. He pointed out the fact that I didn't scour the game from head to toe to check for termites, missing pieces, bad smells coming from inside the cabinet, or other problems, however something about this deal sounded good to me. In the end I guess I got really lucky since the game is in excellent shape, and pretty much he told me if I get tired of the game he would be interested in buying it back. Apparently he's had this game in his "circle" for several years, he's sold it to different people over the years, and either bought it back, or in one case got it back because the gentlemen died. In any case, the game is so much fun I don't think I'll ever sell it back to him!
So far as I can tell none of the mousetraps, or ramps have any cracks, or problems with them. It looks like maybe the plastic shield on the outside of the center "up" ramp, is slightly mis-aligned, but it doesnt' affect game play at all. Since it works well, I'm hesitant to open it up and start "fixing" it.
Anyway, thanks mucho-mucho for the advice on getting this pin as opposed to Gameshow, or Pinbot. Someday I'd like to get into the pinbot/Bride of Pinbot line of pinballs, but it seems like if you get one of those, you'll want to get the entire set - they go together! And I don't really have any extra room for such a esoteric collection at the moment. As it is, I think Old Chicago may have to go..
