where did you get a NEW one from?
if by "new" you mean "ISR" or "Mishimoto", you'd be better off just taking an old oem one and having it rebuilt

I've seen a few of the aftermarket ones fail in under a year.

theres a local rebuilder near me who ive had rebuild a few starters and alternators with zero failures, and only around $100, and they come back looking brand new.

there is probably something similar in your area.
