This is what I have been using,thinking it would blow after a few runs (only $30):http://www.hobbyking.com/hobbyking/store/__28223__HobbyKing_90A_Boat_ESC_4A_SBEC.html
Hoping to try this one out when I get my other project done:http://www.hobbyking.com/hobbyking/store/__8945__Turnigy_Marine_80A_HV_Brushless_Boat_ESC.html
Problem with that is you need a way to power the receiver. You might want to try the 120a 6s version, its only $43. I filled up my four wheelers the other day, It is cheaper to just buy batteries and ESC's instead of gas!
The 90a ESC has settings for soft/hard brake(if I remember right) and it does have neutral. Works just like a car ESC. I find the braking much better, because of the lack of motor squeal. I should mention that I am using it on a 5065 size motor. I haven't tried it on my other board yet, might have to. I actually didn't think it would last for long because it wasn't going to be water cooled, but it runs cooler than my 150a HK car esc.
Startup is also smooth, no problems there. I also tried the airplane ESC with a car ESC for a bit on my dual motor emt and it would throw me off when the airplane ESC did sync. The boat ESC is more like the car ESC starts. I do always push off, both for myself and the sake of the motors.
