Dont touch an Mtroniks if you want to avoid your ESC's blowing up. When I was using mine I think I got through about 4 on warranty. They're very good when it comes to customer support, and I got a speedo with a lower motor limit once, but it doesnt take away the fact that they die pretty often.
I agree with X2. You should get an MRT MX. I've had mine for almost a year (since they were released). It is very easy to use and I've had no problems whatsoever.
