Hi, I'm also looking to replace the motor on my Bernina 117 and Pfaff 130 by more powerful and slowest ones. Of course I want to keep them both portable as well. I have been looking around into the web and found these videos and I must admit I'm quite impressed by the power and the speed this guy was able to get with its Power Cat motor.

By any chance anybody has heard about it already or tested it ? It looks like a stepper motor with speed controller or am I wrong ?
thks in advance. Bertrand
