The Dumas motor is a good one, low current draw which means long run times and a fair amount of torque. Even if you find a used one it is worth getting, built very well. I'm not too fond of the Dumas hardware do to the fact gears are noisy. Yes they make a simple and easy setup but I either install a large enough motor to go direct drive or use timing pulleys and belts. The last Vantec that I bought was 4 years ago and it cost me $80. Technology has made them smaller and a little cheeper. There are several club members in the club that I belong to that still use them, still going strong after all these years.
