Most people go for bigger tanks because they say bigger is better. I bought this tank (used, but in perfect condition) and was amazed at how much room was in it. I've never tried an all in one, and I'm glad that I have now. It's alot easier. With my 30 gallon I had to buy everything individual and it has cost me an arm and a leg, but with this one I modded it slightly and it has been all under $200. I would definately recommend Nanos to anyone.
