Rock Band 3: Pro Guitar controller

[Torque]

So, I'm on the hunt for one of these damned things. I've been taking guitar lessons for a few months, and frankly, my teacher is a complete dink. He's teaching me to play "mary had a little lamb", a few bars of "Ode to Joy" and other shit like this. It's poor teaching, and I'm a little fed up with it, so I'm ending the lessons at the end of this month.
So I decided I will dedicate myself to learning the guitar by using the new mustang controller.
Problem is.... I can't find one!
Anywhere!
No one carries it! I know it's out, but there are none in this damned city. Does anyone know why this is?? Any word on if the periferals are having problems or something? Mass recalls?
