I just got back from the mall and they have a really nice condition Simpsons game from 1991. It's a 4 player beat em up , which I'm sure most of you have played before. Anyways , I have never bought a full size arcade cabinet before , and I am looking into buying this game , because it was one of my favorites as a kid , and because it never came out on any console(to my knowledge). How much do you think this thing is worth? I was thinking around 500-600 bucks , which is the most I would pay for one. Please give me some advice. Thanks alot
