ZOMG so I looked everywhere for a set of Rock Band 2 wireless drums. Out of all of the Targets, Walmarts, Best Buys, Radio Shacks, and GameStops in the area, I found ONE set. It was at a GameStop buried underneath a bunch of Rock Band/Guitar Hero crap. I saw it on the bottom, and I said "I wanna get that wireless drum set there". He looked over at his manager and told him what I just said. The manager looked over at the pile and said "we don't have any..." and then a very shocked look came over his face (I assume when he saw it) and he finished his sentence with "oh... wow". He checked the computer and said "well, that's our only one".
Ha ha!!! I'm sure I had a very satisfied look upon my face when I walked out the door with it.
And the drums are pretty sweet. It's going to take me awhile to get the foot pedal down right.
