It sounds like with that many miles it was probably well taken care of and thus shouldn't have much internal damage that would dictate needing to go w/ a reman.

Check out the parts, make sure the housings arent' flaking, the rotor tips are still straight and solid, replace the rotor bearings even if they dont look bad, check the step wear on the irons and all should be well. Even if there is some level of wear on the irons, you can usually send them off to be lapped and it'll be perfect again - you can always make the adjustment on lapped irons when you spec out the end play at the end of the rebuild.

I say go for it - also, using a guy like Kevin is a plus as others mentioned since he'd know exactly how to measure the wear and whats reusable and whats not (plus a mild port would be a bonus).
