Maybe $30. I don't think there's much demand for these things anymore. I switched to an Advance since every game finally became color/advance only, otherwise I'd still be using my GB Pocket!
i just bought two gameboys plus 4 games,a gameboy case,two chargers,game geinie for gameboy,and a screen enlarger for only $30.good price for all that i think!
Not much. You might as well just hang on to it. It might be worth more later down the road. (kind of like how atari made a slight comeback). I still like to play my classic GB games. Tetris! Oh yeah.
