This was the seller I got it from
AUTOLUMINATE
I chose him because he had the better customer rating and is located near me in Los Angeles, also his kits have a 2 year warranty, but you know how these ebay companies are......
Also found out that the kit is made in Japan
for Hella 4000 you'll need the H1 kit and for the Hella 500 the H3 kit.
When I was over at Kartek I noticed the ballast used in the Hella HID 4000's looked identical to the one's I got from eBay. Considering they only pull 35w. yes I'd say they are tolerated much better......
here's the thread at TTORA, several people over there have done this conversion.....
