Just look for some used SPL or Battleversions on Zilvia. They're always floating around there. PBM stuff is pretty good from what I've heard. I know its popular out in california with the drift kids.

I'd buy Def's RSB's if there where any left. Looks like I'm stuck with going to SPL for it. Thats probably what I'm going to spend part of my tax return on, Stock uprights and RSB's
