I'm thinking about getting an aquarium for my office at work and I'm seriously thinking about getting one of these. The price isn't that bad if you add up what it would cost to buy the parts individually. In addition to that, everything is already integrated into the system so as to eliminate the unsightly equipment.
If it wasn't for the $650+ price tag and the fact that I could definately use the $650 I would spend on this system to buy equipment that I still need for the tank in my house first, I would definately buy one of these.
