I got my kits from DDM Tuning. I'm local to them (The huntington beach, CA store), and so mine were not shipped from China. As far as I know, they ship them out of the San Diego, CA store (Main office).

They apparently offer a lifetime warranty on their kits. (Or at least did at the time I purchased them 4+ months ago).

$50 for a kit that includes two bulbs, two ballasts, and minor instructions.

I got the 55w 6000K color. They say the 55w washes the color a bit, so the 6000K 55w are bright white. 5000K is still a good choice though. They have a chart on their website. http://ddmtuning.com/
