JLevi has an AWESOME set, closest thing to OEM you are going to get.
You can always pick up OEM Xenons from ebay or other board members here or other forums as well.
I am suprised your Dealer actually gave you a quote; most members get the "that cant be done on a non-xenon car" speal from the stealership. JLevi sells his Projector46 kits for ~$600 w/o phosphyre halos and ~$900 w/. I would suggest w/ halos, because phos halos are soooo damn sexy! JLevi is a good company to deal with, the main guy is a bimmer fanatic like us all and he is very helpful.
