I personally like the random modes it has, a more gentle and a more rapid change are the two it has, so you can go through lots of current, a little current, back to lots, little, smaller, higher etc.
That being said the Vortechs are high end pump like tunze + "wavemaker" like tunze add on, but they also have the nice ability to make a wire free tank. Lots of money, yes, but IMO it can be worth it. If you have modded maxijets use those for now until you think you can live with them or not, there is nothing wrong with them either.
Also keep an eye out for used Tunzes, I've seen a lot out there going for very cheap because of the newer models that are coming out.
