I just bought a Exedy/Daiken clutch from this site.

It was $115 shipped for a new clutch disk (organic), pressure plate, pilot bearing, throwout bearing and alignment tool. I was worried it would be junk considering the price but I'm going back to school so money's real tight and about 2000 miles later, I have no complaints. The stock clutch disk I pulled out had Daiken stamped on it too and their made by Exedy. I don't know if I'd try to push a turbo or nitrous system through it, but for a stock replacement like my car, it's seems fine and I can't argue with the price.
