As for the eBay classified from LightWerkz, they do a good job. The only concern I would have would be the contents in the "various adapters" bag. I think they would, but hope that the crush ring is in there with the stuff. Now like stated before, The Retrofit Source is a super great place. Matt and his team are superb in customer service, everything is prompt, and always there for support.

This is what you would be looking at from TRS, Bi-xenon: Morimoto Mini H1 4.1 - HID Projectors from The Retrofit Source Inc

As for the HIDs, I actually just bought the complete set from TRS: Bi-xenon Morimoto Mini Stage III Kit (H1) - Complete Retrofit Kits from The Retrofit Source Inc

The price is a little more steep as the Morimoto HIDs are a lot better build quality than say eBay or other cheap HIDs. If you have the spare coin, I would encourage to go for the complete kit.

Or you could go with either VVME or DDM, I prefer VVME but have heard both sides to both companies. So it's really up to you.
