just noticed this section and noticed that TRS (theretrofitsource.com) has not been mentioned.
anyone that wants to do an OEM retrofit...go here!! i've placed several orders w/ matt, and have always received excellent service. from packaged discounts, to free shipping for HIDplanet.com members, matt is a customer focused guy. i have always received prompt replies to emails, and tracking numbers are always sent for orders even before the item leaves his warehouse.
TRS is also so focuses on providing customers excellent HID products, that they have made several of their own shrouds, improved on OEM projectors (just go read about the FX-Rs, soon to be released S-2000Rs), and make clear lenses available for many popular projectors. they even sell what they call blems (but i have never found anything wrong w/ them!) to save a few bucks. all this R&D to provide customers w/ the best possible HID experience shows me how dedicated they are to their customers.
check my sig for what you can do w/ their products!!
