I've had several different brake controllers, and my opinion is that 'simpler is better'. Had some of the 'electronic' ones with digital read-outs and cappuchino-makers, and they just sucked (they'd overload, and just quit working, which SUCKS anyway that you'd look at it !). I've got a digital Draw-tite and some other piece of trash sitting on the shelf, removed after 3 months use. If you want it, I'd be happy to sell it to you, if you sign a waiver releasing me of all liability.

Tekonsha Voyager (or equivalent) is tops, IMO. Will handle anything up to 3 axles w/brakes on all of'em. You can get a GREAT brake controller for $50-70.
