The Dynamixel AX-12A Smart Serial Servo from Robotis is the most advanced actuator on the market in this price range and has become the defacto standard for the next generation of hobby robotics. The Robotis AX servo product line features a simple, and robust, TTL level communication protocol. Over a single TTL signal line you can daisy chain several servos and position of several servos independently and read back their positions.
From Robotis, the CM-2+ is the controller board used to control the Dynamixel DX-series, RX-series servos that support RS-485 and AX-series servos which support TTL level.
