Alternatively you could use a Dewalt or other drill transmission assuming that it uses an anti-back-drive mechanism.
Continuously running any motor in a stalled state is never a good idea. Even a hobby servo doesn't like it. Position feedback keeps the servo in a set position. Once the desired position is achieved, motor current is removed.

Your best bet is to keep the mechanism you are positioning in balance. That way, the motor is primarily used to move the mechanism, not hold it.
