Best Buy in Lubbock, Texas had only Trauma Center, Rayman, and Super Monkey Ball. No controllers, sadly (I wanted to practice with something other than my TV remote, heh..). I did notice that they had about 25 copies of Trauma Center though, which I thought was pretty cool. It felt good going through all the Wii game cases... hehe.
Another thought, I have no idea if anyone has mentioned this or not, so sorry if it has been, but the GGCs WILL work for controllers, and since they are 2 pieces, they work doubly. $50 controllers are much better than $60 ones.
