Although its hit or miss with the eBay kits I got the "xentec" brand hids off of eBay and knock on wood I've yet to have a problem with them. I've used the same ballasts in all three of my trucks an never had an issue. The only problem is I get flashed all the time like I have my brights on but I don't even have brights so I tend to feel like a jerk. Not to badmouth retro solutions by any means because I've seen some of the work and kits around on this website and it's amazing but at the same time my 40 dollar hid kit is pretty bright for being some cheap knock off and I've had zero issues with the kit itself. I'm probably just the luck one this time though. Lol
