NO! I usually just prewind a bunch of bobbins before I start on a project.
I do, however, have a bobbin winder with a foot pedal to regulate the speed ... it is for my LA but will work on my regular sewing machine bobbins also. I prefer it much more than I'd ever like a Sidewinder. Got it from a LA dealer/LQS.
Though ... I tend to be overly frugal. [OK ... cheap.]
