Anyone still use a Mamba Max?

[Revracer]

So does anyone still use a MM in conversions? I used one with a Rx pack in my revo running 3s lipo on my mega motor. I am about to get 4s lipo and havent used it in a while. I really dont have the money to spend on a MMM or similar ESC. With what Im geared my truck is tuned for just at 40mph on 4s lipo with my Mega. Its rated for only 70a max. Anyone know a good ESC for cheap or should I just keep using my MM?
