Jx - I replaced my window regulators on my former 330 and from experience, I would go for the ones that either Bavarian, Pelican Parts, Autohauz, or one of the sponsors offer. Not that its a huge deal to replace, but I would not want to keep on doing it by skimping on cheap regulator.
Word of advice, when you replace, be careful with the connecting/disconnecting of the airbag.... You dont want to end up with an SRS light on ur dash.... Good Luck !!!
