Ya, my previously mentioned non-gaming period ended about 6 months ago, so I never picked up RB3, I wanted to try those pro-drums SO BAD. But now im headed to college and cant justify the money.
It does suck. Those drums can cost a few hundred dollars and with the ending of DLC (April 2nd), it's gonna be tough to get new instruments or even buy a PS3 copy (apparently they're pretty rare now).
Still, the game is a blast even when alone.
