servo amp recommendation

I'm using a BS2 which only sources up to 20mA. I would like to use a digital servo that stall current is about 850mA. Is there a driver or amplifier available through parallax that might suit my needs or another amp or driver that could be used?

    The stall current does not affect the signal line regarding the I/O pin.· You need to make sure that your power source can handle at least 1 amp.·

    Yes. The "Power" pin is different from the "Signal" pin. The "Power" pin will route the current from "Power" to "Ground". The "Signal" pin does not take that much power, but signals the desired output shaft position.
