Somewhat cheaper agreed, but kinda weighing up what the budget can stretch to. That one looks pretty tall also, and I guess id either have to remove the fan to mount it on the motor plate, or leave the fan on and mount it behind the servo........... which of course then forces you to buy a low profile servo.
