Haha, just traded my gamecube into gazelle for $4.00 last week, would have gladly given it to you for $10 or so shipped. It was in perfect condition too, just figured no one would want it and I just wanted to get rid of it. I didn't trade either of my controllers in though, I kept those for the Wii. I'm sure there are plenty of people who have them laying around just collecting dust though, someone has to have a good deal.
If you would have just posted this a week ago, it would have been yours.
