I used to have a Prodigy P2 controller which went bad. I never liked it too much as I had to readjust from town to highway.
I went to a Brakesmart but sadly it is not made anymore because it is an awesome controller.
That said one of my camping friends has a Hensley Trucontrol and the other has the Direclink with disk brakes. Both seem to love their setup.
If I were looking for another controller I would probably go for the Hensley Trucontrol as I don't like the cord hanging down on the Direclink.
You may want to compare amperage output, electric over hydraulic capability, does it tell you if there is a short (bad brake magnet), etc......
