So I've been saving up for one of these badboyz. I really like the lighting choices. Im looking at The 12g 54w system which gets me 4.5watts per gallon and the 24g 64w system with2.6 watts per gallon. The 12g Nano cube has the same lighting as the 12g AP but the AP is much cheaper is there much difference between the brands? I'm pretty much can spend about $200 and under
