RE: align esc cut off
This is one I bought off Tower and received it today:

I got the 5amp one and installed it and it works great. It has adjustable voltage and also has a low voltage buzzer that's adjustable. Interestingly the instructions said to disconnect the power line from the ESC connector, so I did. The instructions said it could handle up to 11 digital servos so I assume the 3amp would do just fine for $24.
