I am really surprised more people don't do the HID projector route. No matter how much engineering and money designers dump into a reflector housing it will never be as good as a projector. The beam from a projector is much more crisp, puts the light in places you need it much better and doesn't shoot light where you don't need it. There is a reason that almost all new cars regardless of whether or not they are HID or halogen use projectors rather than reflectors. A projector can shoot a much more even beam than a reflector can and doesn't shoot any light above the cutoff so it doesn't get in the eyes of oncoming traffic.
I just purchased everything I will need from a harness, projectors, HID kit, and new housings to hack up to install the projectors into and so far my total is at $95. I will make sure to post my results when they are completed, but personally I think bixenon projectors are a much better way to go.
