whats the best blowoff vavle for a 9000?

coming from the import world im used to names like greddy, hks, turbo xs, apexi and stuff like that...but i figured a saab specific one would be better...so whats the best one for the money?

Forge seems to be popular amoung Saab owners (and Audis?) but personally I think japanese BOVs like HKS, Blitz or Greddy are better. I have Apexi Twin Chamber BOV and am very happy with it.
