Don't have one myself, but I know someone who has one. Only complaint is the noise from the belt/pulley system. He said it was a little annoying. Good water movement and backflow.

For the price and footprint, I'd go with a vortech mp20. Don't know how much wave you'll get on a 30" tank since occilations will be fast. But the mp20 will give you more flow options besides standing waves.
