how many gallons is the sump? I see your thread were you are thinking about getting the 150, kinda in the same boat, what I'm going to do is get a used 55gallon and have the hardware store cut a few pieces of glass for baffles, so i can have it set up exactly the way i want it..honestly i dont think i would spend the money on a sump since its so easy to convert an old tank to one....just my honest opinion, wish that 150 was in my nieghborhood i would have beat you to it...
