I have the aquatinics constellation fixture - 7 t-5 bulbs that you were speaking of.
I faced the same sort of decision as you did - however, my tank is a 90 gallon. I wanted a fixture that would work on a 120 gallon if I chose to upgrade.
However, I decided to not have a canopy, and so the fans were important to me, as well as one extra bulb. The ballasts are overdriven, so keeping the heat down is important for the life of the bulb.
My fixture is not housed in a canopy, but hangs instead. I totally love it! It has three seperate switches with three seperate power cords. This enables quite a bit of flexibility in regards to lighting schedule - and is nice to be able to reduce lighting to acclimatize new occupants. I have each cord on its own timer - set it and forget it.
Can't say anything about sps corals - I'm just a newbie, and tank has only been up a couple of months, so I am slowly adding beginner type corals - no sps yet.
