CC has talked about the MMM for easily way over a year. I was originally planning to wait for it for my buggy, but grew tired. I just went with the MM, and if it works out all right, then there will be no need for the MMM for me.
The only way I would buy the whole CC package (esc and motor) is if besides for running as well as a Neu or Lehner, the price was lower for both together, than a MM and Neu/Lehner.
