hehe talk about reviving an old thread. Anyways, I had to return those d1S ultinons; they had faulty bases (I switched back to my stock osrams in the headlights... still using the ultinons on my foglights however).
It will be hard to get a decent set of D2S bulbs in 6000k for 50bucks (almost impossible actually); ebay has plenty for ~30bucks shipped, but there are no guarantees. Your best bet would be to pick-up another set of stock 4100-4300k bulbs.
oh, and to my understanding, you're supposed to keep the housing reflector along with the H4/D1S shield. They're meant to fit H4 housings without any modification, and most H4 housings have a reflector. BTW, these guys seem to have the best deal on the shields
