One of my local fry's has some wii rb1 guitars on clearance for $18. Based on reviews, it looks like the rb2 is more refined, but nonetheless, the rb1 guitar would be an upgrade to the new les pauls I have, and for $18, it'd still be a great deal. But the les paul controllers use a wiimote. Do the rb1 guitars sync via bluetooth? Or is there a usb dongle? If so, would it only come with the complete game package? Or would the solo guitar come with one too?
