Digital Ballast Experiences/Recommendations

Getting ready to buy my growlight in the next couple days, but all of a sudden today I start reading about all the bad stuff associated with digital ballasts. That Lumatek had ones that were shorting out lights, and causing detectable RF interference in a wide area (neighbors houses as well). However, from what I gather across a couple posts, this seems to be a fixed problem. I haven't been able to catch recent posts regarding digital ballasts, so is there anyone here that uses them? Can anyone give recommendations? I was looking at Lumatek, Vue (Zandor recommended), and Project X (from www.texashydroponics.com). Thanks to all that reply.

Don't know if you've read this... it's a link to a BGHydro FAQ about digital ballasts.

I haven't used them... they sound cool...

I'm running 4 600w Lumatek's no interferance probs with them, the closest radio is aprox 20-25 feet away but no problems with it...
