The Sabertooth 2x25 by Dimension Engineering is really a giant in a small package. It provides everything and more than I need. The DIP switches allow it to be programmed to control the mower any way you choose. It has a built in fail safe that shuts down the system if you lose RC signal. The 5 vdc regulated power supply provides adequate current for most RC systems. The specs say that if you load it up with too many servos it may require additional power, but since I am not using any servos there is no problem. My Sabertooth is mounted directly to a steel plate and I have not noticed any heat build up. I am sure this unit is capable of much more than I am using. It comes with 4x40 mounting bolts for easy mounting.
