I need to resume working on the PS pump, and A/C compressor. I've been advised here to stay away from "big box" parts, which I am fine to do, since I've had two PS pumps from one of those big box places, and both were just as bad as the worn out one they replaced.

I'm seeing fine deals eBay for reman and new PS pumps and A/C compressors, but I don't know which brands to trust. I've heard Dorman is good, but I'm seeing more Cardone and Sanden.

What's good, and what's not? I understand that the vendor and their level of honesty has something to do with this, but assuming honest people and truth in advertising, what's a good brand to go with generally?

Thanks.
