I'm interested in a guitar for my Wii. I've played at friends before and i intend to get my own.

1) Anyone know how much is a standalone Wii guitar? (good as second player guitar)
2) is there original or alternatives?
3) can guitar play both GH and Rock Band? i heard from someone claiming they are not compatible. True?

That's good!

Does the mic comes with the set?

Someone told me that he can't GHWT without guitar. something bout at a minimum he needed the mic, else can't lay the game with the wiimote.

I know that's possible with the previous version (Guitar Hero Aerosmith)
