As a relatively new quilter, the first time I FMQ'd it was with the on/off button. I like it because you can really concentrate on getting an even speed with your hands without having to think about your foot pedal. When I upgraded to another brand without an on/off button, I missed it so much I upgraded again. This time I not only have an on/off button, but I can also stop my machine by tapping the foot pedal too.
