I have had the same experience with the Hacker controller. I have an 18.97 in the tc3 now (not the kw/kwf - no heatsink) and I can't complain. I think the smaller motors have a slight advantage in acceleration, but the setup I have now is definately no slouch(don't think I need it to be any quicker!)! I have heard good things about the u-force, but I haven't tried one. Schulze is not famous for warranty backing (in fact, they always find a reason it was the users fault!). They are slow to turn things around, too. But that is partially because they are so far away. BK is definately quicker and seems to back their product pretty well, too (not that Schulze doesn't have killer stuff, but when it fails, it gets expensive - and they aren't cheap to begin with!). I have heard good things about the mgm controllers, too.
i am set up as a dealer with them, too. I just haven't had the budgetary means to add them to the lineup yet.
