I realize the OP was a while back, but I have been using a Difalco 302 for a few years now. Absolutely wonderful. The spring on the ball bearing mounted trigger is just right for me. The adjustable pots for sensitivity, braking and “traction control” are stable and reliable 
Maybe the best part of the deal is Jim Difalco’s customer service. I wish they were all this good!
I read that he has just released a new high-end 1/32 scale controller. Can’t remember the details, but I’m sure his website has the info.
