Does someone make a superior throwout bearing?

I've only had good luck with the BCA 614036. The SKF and Timken made stuff seems go go away very quickly. You should also make sure things are adjusted properly and that all the springs are on the linkage. I've also seen more than one killed by adjusting it too tightly so the bearing can never totally release, and where a pressure plate did not sit properly because the flywheel wasn't surfaced.
