I always go with factory original parts when they are still available. Yeah, they might be more expensive, but I'm not a fan of a lot of aftermarket parts out there. I hear about too many problems with bushings not lasting very long. I'm sure there are a few good ones, however, you pay for what you get. Cheaper is definately not better. I'm still running all the original control arms/trailing arms and it's been 12 years now.
