I had bad luck with cheap aftermarket axles before (premature ripped boots, bad vibration, etc). I have a set of Raxles that are really nice, but if that's more than you want to spend, get an OEM axle in good shape and put some new boots on it. OEM, if they haven't been run dry will last forever.
OEM will be the best then under them is Raxles. EMPI also makes axles, I dont think they're remanufactured though. Driveshaft Shop also makes performance axles for the b13 or b14
