GameCube Question??

That would probably only be worth $100 now.

100-150 tops.

Not many people interested in the Nintendo Gamecube since the Nintendo Wii can play gamecube games anyway. Most prefer to just buy the Wii. If you expect for people to buy your console, don't sell it being too expensive.

Goodluck.

maybe $240 but it depends on the capacity of the memory card and if the controllers are wireless and the type of games1028209

It should go around 150-200$
