If you can build a canopy that you'll like I also vote for DIY or a retro kit. I also second the recommendation for ATI bulbs. Current USA bulbs are junk and I was not impressed with the 15K AquaScience bulb I tried. I think Giessmann (spelling?) are the same as ATI.

Also I think 8 bulbs might be overkill. Really depends on tank depth, a little on volume and the types of corals are your keeping. I only have three bulbs on a 50 breeder and keep all but the highest light demanding corals and clams.

HTH,
