Rebuilt stock a/c compressor or what?

[nyncompute]

It's time to turn my attention to the a/c portion of my under hood makeover. I've gone through most of the components, the condenser, evaporator etc.

But the A6 compressor: It seemed to be in good shape when I pulled it over a two years ago. I noticed it was remanufactured. I'll be sticking with R12.
Should I:

1) stick with the unit I have..it seemed to be functional enough. It held a charge and the clutch worked fine (again 2 years ago).
2) get another remanned one (if so what brand) as a precaution.
3) bite the bullet and buy a new one. Are there several makers for the A6?
