Why is it, no one sells just the Wireless Guitar for Wii? I bought the bundle with game for $90, and would like to play Co Op, but no store sells just the guitar? WTF?
try a game store, could find one used, unlikely, but it's possible. i know the gamestop by me had at least one at one point cause i traded it in after i sold my wii! lol
Just buy another bundle if you can and then sell the game itself on eBay or something. I've seen the games alone go for $20-30 on eBay (assuming its sealed), which puts you at around the cost of a guitar alone (unfortunately as Activision seems to like to rape Wii owners on the cost of the guitar despite all the technology being in the Wiimote).
You're just going through what other first generation GH players went through.
If you want it now, you have to buy another guitar+game package. That's what I had to do to get another guitar.
