I bought one of those crystal controllers from the site posted and it came today. It looks really awesome, but unfortunately it's pretty screwed up. The A, B, X, and Y buttons don't work well at all. They only respond 1/2 the time and only when you press down really hard. The Back button arrow isn't facing back, it's stuck pointing up. And worst of all, the slot for the communicator doesn't work either. When you hook up the communicator and mic, the light goes on but you can't be heard. I switched controller back to my old one and it was fine.
I emailed the site but they are closed till Monday. Hopefully I get a refund or exchange...
