Digital Greenhouse Lights, Good Value or Not?

I was looking at these lights at HTG and they seem pretty reasonably priced compared to some of the other units out there. Does anyone know if they are good quality or not?

Ok, so I'll take your overwhelming silence to mean that nobody has tried these. From the additional poking around that I've done and from some of the other comments that I've read, it seems that Lumatek is well accepted and that Future Bright has been around for a while and then there's Galaxy, eLux and Infinity for which there is little documentation. HTG and HIDHut have their own brands that are packaged systems with ballast, bulb and reflector for really cheap, but that just makes me suspicious. If anyone else has anything to say about it, by all means, do so.

My Digital Greenhouse electronic ballast is great, no problems.

Any problems with RF Interference?

Is getting a digital over magnetic worth the extra cost? They sound promising, but is it just hype?
