As you get into this, I would like to particpate. I was quite upset when I bought mine under the supposed ability to contol them with wavemakers. When I found out that they couldn't be controlled with my AC III Pro, I was crushed. I have spent a crapload of money on the pumps and my controller system, and it just doesn't make sense that these companies cannot build in cross-product compatibility. I understand it from Eco-Tech's position, since they can get better penetration with their own controller, but for the higher-end market, I think it's a must to give the customer more than one option.
We are still in the infant stage with the Vortech, and I am sure they will continually release better controllers. In five years we will probably see units with LCD screens, main system modules, software, etc. It's just so hard to wait. Right now, because of heat issues, I can only run my pumps at about 50 - 60% (who the hell really knows?) so my tank is getting much too little flow.
If you have any brainstorms on mounting a CPU style fan on the motor and linking it to the power supply, I would love to hear about it. I envision an aluminum heat sink tacked onto the motor housing and a fan unit that clips in and connects to the power supply. Getting it to be variable based on pump temp. would be sweet too. What's funny about that is IceCap is one of the leaders in variable speed fans!

Right now I have one pump with a dedicated fan that is running at 100% with zero problems.
