I have kind of a soft spot for Jet Spin. I had been out of the hobby for a long, long time when I ran across one in an arcade in Hoover AL while I was killing time one day in 2010. I never really was all that interested in the later SS/DMD games, I didn't play much pinball after about 1985. I really lost touch with it and even though I still owned one game it was stored and hadn't been played in a long, long time. I didn't know that anyone even still had any interest in EMs or that forums like this existed. Or, that parts were even still available.
So I spent probably 5 hours playing that Jet Spin and it was like I'd never been away. I talked to the kid at the counter and he told me that there were tons of people still interested in EMs, told me about Steve Young. I came home, set my game up, got parts from Steve and got it running again. That led to another game, and another, and another...we all know the drill.
I've owned two Gottlieb multiplayers since then. Surf Champ, which I sold a couple years ago, and Big Indian, which I own now. I'd say BI is a slightly better player, and also easier to maintain due to the lack of the Ax/Bx nonsense. Surf Champ is pretty good, though, with the drops roughly in the same places as BI has them, the spinner, and the kickout hole.
I also like Hot Shot, Jumping Jack and Target Alpha ok. If we weren't limited to Gottlieb, I'd easily take Space Mission and Grand Prix. Great players
