David,
go for the DEPO Projector 36 (P36), they look very close to how the newer cars look. The Halos illuminate Halogen "yellow" and you can upgrade to Xenon HID's on the lights, but the H7 bulbs that come with them work/look just fine. I have these on my car and they look really nice!...Although I got them from a vendor on ebay and not ddm, less than $200 shipped... I posted the link on the thread about "will these fit my 97 ti" on ebay listings thread.
I'll make it easier for you....here's the link
