If all three have a 3/4 hp servo motor, what is the difference between a consew 206rb-5, chandler 406rb, and a Juki 1541S? If I go with either of these, they would have a gear reduction/speed reducer for controlled work. If I don't go with either of these, I am leaning towards a Cowboy 3500...but that is a different beast of course...so for this topic let's please just compare the Consew, Chandler, and Juki machines mentioned above.
