HID conversion kits
 

I am planning to convert my fog lights to HID myself, but not sure of a couple of things.
1. What is a very good brand to buy? I know MTEC makes good HID conversion kits, but they dont make H10/9145 (fog light)kits.
2. Does the type of ballast matter? what I mean is whether digital ballasts are better.
3. What is a good temperature color for the fog lights? I was thinking of 8000K.

I would do the driving lights too, but as many of you know, the plastic harness is almost impossible to take out...I know b/c I have already tried with no luck.
Any advice would definitely help me out. Thanks
