We like the motor a lot too. It's been very reliable. I DO have concerns about adding a speed reducer into the mix, as I have not had a lot of luck with my testing. I love the simple plus and minus button that makes it easy to change speed at 100RPM at a time without a complex timed button sequence. Also, the motor is a real torque monster, and may not even need a reducer, but depending on your work, the reducer is key.
As for the motor, your FedEx shipment was canceled, not your order. This morning she said that the motor is on the way, scheduled for delivery today via UPS. All the best, glad that you are enjoying the motor.
