I don't know much about the game, but it books for $550. Since it's broken I'd say $200 or $250 less for a fair deal. If you want a good deal I don't think $100 is crazy.
I don't know what the above poster is thinking, but if ems sold for $3,000 not only would you not be able to frequently pick them up for $100 ish unrestored but I'd have a new career. Even if you restenciled the cab, had a nos back glass and a nos play field, I think it would still be a $900 game instead of a $500 game unless it was one of the gems, but that's the exception.
