All the new ASP pullies are SFI certified. There are other companies that are also selling SFI approved versions. If you don't plan on running 10's any pully will do. The ASP seems to be the most popular choice.

i've noticed a couple of people that are changing out their sfi pullies for the newer march sfi pullies or ati pullies(higher hp applications), so you're bound to find some asp sfi pullies in the for sale section
