How much should i sell this for?

Depending on the game, and the weight and size of the game, i would say anywhere from $900-$3000 could be the right amount. Try comparing it to other people selling arcade games. You don't want the price too high because no one will buy it, and you don't want it too low, because you will barley make money off of it. So check out E-Bay or Craig's List, and see the other prices. The website i left at the bottom lists a few prices for used and new arcade games. They are around $2000, so maybe that's the right amount. Hope I Helped ;).
