I remember having a terrible time finding one when they first came out. The hype was big but the system never clicked with me the way the Gamecube did the years before. A couple summers ago I bought a console for a dollar at a yard sale. How the times have changed.
They sure have, people never played them much so there's an abundance of systems in great condition. Good time to get a Wii, i picked up a CIB black model with gamecube support for $50 cad. I really wanted the black model and needed the gamescube support so was willing to pay a bit more. If you arent picky about the model they can be found for dirt cheap. Its at the point where people are clearing out their basements full of barely used Wii stuff.
I really just bought it to use as a gamecube and a couple games on it like Super Mario Galaxy. Really wish that game supported gamecube controllers
Also a great time for ps3 and xbox 360 games. I occasionally pick up a dozen ps3 games for $20-30. I dont really bother with the 360 because of the paid online.
