Okay I need some advice on some gamecube controllers. Ive heard from many sources that the best way to go when it comes to gamecube controllers is to get 4 wavebirds. Dont get me wrong, I think the wavebirds are great, other than one thing: Rumble. This may not seem like a big deal, but sometimes I just feel like playing with rumble on, and with 4 wavebirds you have no choice. So, the main question is has anyone ever seen/heard of a wireless controller with rumble capability. I really think there is no such thing for the gamecube, but hell, why not ask. I really like the Madcatz wireless microcon, but again, no rumble. So I was thinking about getting a Madcatz microcon (with a wire, which really annoys me) but that has rumble, along with 3 wavebirds. Thoughts?
