I  have used the Allglass strip on a 33 gallon tank with a great deal of success.  Interestingly I bought the light at Big Al's here in Calgary, and paid $250.00 for it. 

ops:   I currently have the 2x96W fixture you described on order for my 50 Gallon reef.  I have ordered it from MOPS at $329.00.  The address for mops is
