Does anyone here have experience with the NetMedia Servo 8 Torque controller board. Available from: http://www.web-hobbies.com/servo8t.html at $60 post paid. It controls up to 8 servos and provides position and torque feedback for each servo upon request. Looks good for my walker. Any comments about Scott Edwards SSC2 controllers? $44 plus shipping from: http://www.seetron.com/ssc.htm My current walker is a 3 servo guy that only does a tripod gait ... no need for servo controller or torque feedback. My new guy with six 2-DOF legs would probably benefit from position and torque feedback info. Comments? thanks, - Nick -
