I don't have a cube currently but I do have a column which I love. With that said, my next tank will definitely be a cube, and will probably be in the range you are discussing. I love the height that the column brings, and would love if my tank was a cube to add to the depth. It's hard to argue that the ability to view the tank at maximum potential from 3 sides makes the cube an awesome tank. Don't look back, go cube!
