As far as what kit to go with I went with H10's for fogs and H11's for low beams. They were around the 200.00 mark per kit. Now that is high compared to the DDM or retro solutions kits but I can drive 3 minutes down the road and get warranty if need be. It's only been a couple of months with the Beamers but I haven't had an issue.
I got the Beamer kits locally. Not sure where to find them on the net. They are flawless. I had DDM tuning kit installed first with their error eliminators which work very well so my install was literally plug and play.
