What is everyone doing when the servo motors go bad? I have several R2E4 series-2 and one series-1 that need motors. Since you can't buy new ones anymore does anyone have a good solution? I have had some repaired for $800.-$1,200.00 but not all are repairable. Series-2 use Sem. Series-1 use CMC or Powertron. Could I still buy the proper motors and encoders separately and connect them? This is a big problem since repair is a gamble even if the motor components are still good.
