We've begun carrying the Duratrax DE-10 Brushless Speed Control and a couple of their sensored brushless motors, a 10.5T and a 13.5T. The speed control is very programmable (with the optional programming module). The speed control runs $79.99, and the motors are $59.99 each. Right now, it's just a trial run, to see if this is a product we like. If so, we will be carrying these full time.
Only time will tell if this is a good move for us, but I kinda like the idea of a sensored brushless system, purchased à la carte, for only $140.
