I hear you Matt. I can imagine that many powerheads in a tank could distract from the display, but man does this thing work good.
John. If you want a quick, simple, cheap and fast way to set up a wavemaker then I would recommened this unit, but if you have the extra money and want a cleaner non cluttered look like Matt was saying go with the SCWD. The plumbing isn't as taxing or intrusive as you think. You could easily hide the whole thing behind the tank.
