I have two incoming in the next few days, im not sure if i need two wavebirds, if i dont ill be willing to sell one of them.
Also you can check your local stores, but if you're like me or most others you won't find any, but stores to look at? Wal-Mart, Toy's R Us, Gamestop (used here might be your best bet in finding any at any store period), Bestbuy, Circuit City, etc....basically any place that sold Gamecube stuff. Very unlikely you'll find one though, even used at Gamestop is a stretch.
