recommendations of power steering rack refurb companies

I posted this also in my audi a4 forum but was hoping any of you guys out there could help a girl out and recommend a good reliable power steering rack refurb company??

I have heard horror stories about a good refurb and a bad one, with the bad ones only last months as apposed to years.

Has anyone had a good experience with any companies out there and recommend a good one??

I am hoping to order in the next day so any help and advice would be great!!
