I want to buy either guitar hero, or guitar hero 2, does anyone know how much they cost, and if the game comes with the guitar?

Guitar hero I or II will cost you about $75 on amazon.com. That's for the game and the guitar controller.

Guitar Hero 1 and 2 usually run about $75-$80 bucks with a guitar. The games by themselves are about $40, and don't forget about Guitar Hero Encore : Rock of the 80's, which costs about $50.

I have all of them, and they are awesome! I totally recommend them! :)

Usually about 80 bucks at your favorite game store. I like Guitar Here II, but I don't know how much my opinion really counts, being that's the only one I've played... ha ha

Guitar hero is really addicting, how about getting a real guitar :-)...

Please

I would go with guitar hero 2 and I bought 2 controls and it cost me about 120$
