I am looking for a set of 107 euro headlamps. Where's the most reasonable place to find these (assuming I can't find a used set)?

You might try here (Fastlane), Adsitco (may be flakey by some reports), or Performance Products (seems expensive).

Beware!!! I bought used ones and would up spending MORE than new ones would have cost in restoring them. Parts (and this includes seals) are almost unobtainium in the US (except for the headlight lenses, for some reason). Seals are crucial. I had bad seals on the used set I got and had to get the reflector buckets redone at great expense. People have had them chromed but, hard to beleive, this is not as reflective as the original aluminum coating. I also had to make my own adjusters (very crucial to adjust these properly) because the ones on my used set were hopelessly rusted.
