Soooooo.... i might need a new CV shaft (or two)

What ever came of this? Should I steer clear of NAPA and try another brand? Rockauto has a few different brands for CV's....

Since mine arent completely toast yet (trying to track down a popping noise and think it might be one of the joints going), figured I'd replace them with some aftermarket CV's and keep my OEM ones as spares for the trail.
