Krow,
I bought a Hamilton light system last year. Mine is a 36" and has one MH bulb and 2 96w VHO wired seperately so I have them on seperate timers. I'm very happy with it. When I was "shopping" for my lights, I looked at the ones mentioned by lilbuddy. I wanted the MH/VHO combo and the place I got mine was the only place that offered that combination in a 36" hood.
If you're interested in the web site, let me know and I'll get it to you.
Jim
