The PS3 version was for $27 before, glad I was hesitant. This seems like a pretty good deal, finally got my second guitar.
The Xbox 360 version comes with AC/DC Live and Rock Revolution.
Hmm, I was pondering picking up a replacement RB 360 guitar, since the yellow fret on mine seems a bit dodgy as of late. I may just pull the trigger on this. A free AC/DC Track Pack certainly doesn't hurt.
I don't recommend these guitars at all. The guitars from the first Rock Band are extremely low quality and aren't durable at all. I heard the wireless versions are a little bit better, but all I know is I went through 7 of them before I finally gave up on them. And I know I'm not alone on that.
I bought the 360 bundle the last time this deal came around. Definitely an improvement over the wired Rock Band guitar, though still inferior to the Rock Band 2 one.
