I ran a blue bird BMS620MG in my buggy, I think I paid $24 for it and its got 144oz and .13 or .10sec speed and it works great aslong as your radio has EPA. steering you want atleast 140oz of torque and .15 speed, and for throttle you want atleast 85oz of torque and .15 speed the spektrum Z590 is a good cheap throttle servo you can get 2 of them on ebay for $30
