High Quality Ballast

So my 600w ballast just died now I'm looking for a new one and want to buy a high quality one so that it doesn't die on me either. I heard Nexgen and Lumitek are pretty good? I'm not 100% sure but I'd like to hear from some people before I spend some $$$. And If anyone knows of good sites to purchase them from for a good price, that would be very much appreciated. Thanks!

I use a virtual sun ballast and I've had no problems, its still fairly new though. I found these 2 spots to look around.

Not a GYO ballast, mine died before it was even a year old.

I have been rocking Lumateks for years with no problems. I like them because they have no fans. My buddy did buy 12 1000s and have one die after 6-7 cycles but the over the counter warranty made it ok. Mine are the older non dimable ones though so maybe someone can chime in on those

try ebay first
