What are the top T5 HO fixtures currently

I've got a Sunlight Supply Tek Light 48" 6x54w. I bought it because it was decent quality for the money (about $400 before tax). Two power cords/switches: one turns on the first and last bulbs, the other does the four middle bulbs. I like it, my tank is still cycling, so I havn't tried any corals under it yet. The only thing is that there are no fans like the ATI fixtures... I just set up two cooling fans on the side of my tank. It may not be top of the line, but its pretty close. If I was going to spend more on a fixture I would go LED.
