Hey I noticed you mentioned projector HIDs in your future. Why not give these a try, they have a projector lens already built in. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1,1&item=7986233217&sspagename=STRK%3AMEWA%3AIT
I'm sure they're not the same high quality projector like the OEM MBZ or BMW systems use but they're around the same price as the ones you're looking at.
FWIW, I had a set of the Autopals that looked like the euro versions in your post. I was not very happy with them at all. They never fir quite right in the stock bezels (trim rings). I got alot of shaking in the lamp and I was going through bulbs like crazy. My stock halogen lamps and other H4 comversions never did this using the exact same bezels. Just my experience, I know others have not had problems with them.
Also, even with the H4 upgrade, I never got the full light output from the lamps until upgrading the wiring. Check out Pete's site. This mod will help your headlights more than any drop in lamp.
- just my 2 cents
