are you looking for a return pump or a wavemaker?
the speedwave dc does come with a controller for changing speeds, but of course does not have anything like the vortech. I use a Jabao wp40 wavemaker that is pretty well a Chinese knockoff of the Vortech MP series and comes with a controller that does the same thing, it works pretty well, and you can find them for around $100, or even less for the wp25.
