Opinion on remanufactured caliper companies

[Steven Papatrefon]

I also posted this question to the SR20DE forum.  Does anyone have any
opinions on purchasing remanufactured brake calipers from the following
companies:

A1 Cardone
Beck/Arnley
Bendix
Raybestos

Are they all about the same as far as quality of products?  Or should I avoid
one or two of them?  There are some substantial differences in prices between
these companies for the same items.  I know some of you work in the
aftermarket parts field and may have some experiences with these different
manufacturers.

Thanks,
