I have been looking at these myself recently and like the cost.
I am thinking of upgrading from my cheapo hagen fixture on my 36 gallon.
The 24" expandable looks about right for the tank, but I don't like the external fan and have never had external ballasts before.

The ones I got are external ballast for both MH and T5s, I like the external fan that goes above the MH bulb, very quite and can be put an a timer so that they come on with the MH.
