Where is the best place to buy high quality replacement projection headlamp assembly to upgrade my 2004 coupe ?

InfinitipartsUSA sells them for $875, which is about 2-4x other aftermarket options. However, I don't see much of a warranty on several aftermarket sites

I'm tired of polishing the lenses, and other forum members suggest buying a 2006 - later projection headlamp assembly -- for better visibility.....but I can't find a recommended source..

Thanks much,

Used man. Gonna be your best bet for not spending a ton

 

You might want to check the marketplace, I saw 3 sets of projectors for sale under the "lights" section.
