Replacement A/C Compressor sources.

On our way up to North Carolina I had the A/C belt go on my Mazda 5 at 63K. It was either the belt cracked or the compressor seized up. I got to my mechanic today and he looked at it and sure enough it's got a flat spot in it where it's difficult to turn.

He did some looking and couldn't find anybody who made re manufactured units so the only source he has is Mazda directly which isn't cheap. Does anybody have any sources for reman'd units?

Thanks
