Heya Scott. That's a pretty cheap light in that link. Looks awesome but I have never heard of the brand before.
I would def suggest at least a 4 bulb T5 fixture. If you can get individual reflectors for each bulb all the better. I have a setup like that and I am keeping every coral including some sps
Fishneedit.com has some cheap fixtures too, no moonlights though lol. Keep in mind you might have to replace crappy ebay bulbs with good ones if you go the cheap route. I spent $90 on my ATI bulbs, but they are worth every penny.
