What's my cocktail worth?

[The Collector]

This weekend I want to take my Stratovox cocktail table to the MGC. I want to either trade or sell, but i have no idea of its worth. The game works flawlessly and the cabinet is in nice shape. The glass top, of course, has 25 years of scratches on it, but none to obstruct playing the game. Any ideas?

Thanks
