Rebuilt power steering pump VS new

I need a new pump for my 99 Cherokee and so far auto zone's pumps have sucked. I have had to replace it twice because of leaks etc so I'm thinking about just buying a new pump from Morris 4x4 center etc. i realize this does not guarantee anything. Thoughts , anyone have any luck with other sources? Thank you.

On certain parts I am a fan of the SALVAGE YARD, other parts only NEW, never reman, and others reman is usually good enough.

I think I would try and get a very late model OEM pump at a salvage yard, doesn't have to be off an XJ, search there is plenty of info on other pumps that will work.
