I also was having the same problem finding a quality lighting fixture for my 29 gallon tank. I ended up doing a google search for 30" MH Aquarium lighting and found a fixture on ebay for 200 bucks. It had 1 MH, a ballast, 4 atinic t5 and 4 LEDs. Not the best fixture, but it works great for 200 bucks.
I dont think they are listed on ebay anymore, but this wasn't too long ago... maybe 4 months.
