My Pioneer balancer had Powerbond stamped onto it. I don't know if its because I got teh SFI version or they are just all made by powerbond or not. It looks killer and they are not very expensive either. i got mine from http://www.strokermotor.com/DESCatalog/page-4-SFI.html
Non-SFI is around 70 and SFI versions are about 165
i think the first 2 guys are referring to a stock replacement pioneer. I have a pioneer sfi (which has powerbond stamped on it and powerbond documentation in the box, and its partnumber is 872030
