I got the cheap madcatz one they had at Circuit City, it was $20 and it works fine, zipped home and played some Rush 2049 inside of Midway Arcade Treasures 3 for the gamecube on my Wii, pretty cool. I would be pretty interested in the Wavebird too, from everything I have read you would think they either walk on water or could solve global warming.
