I have a similar gadget, but after I had the bobbin winder on my 201 properly adjusted (long overdue), I haven't had it out on the table at all. My old Bernina 730 has always had very fast even winding and the side winder never feel like an advantage with this machine. To anyone considering bying one I would only recommend it if you think bobbin winding on your machine is cumbersome and you have space enough to have it out on the table. It's one more gadget standing around, and I have enough stuff with three machines and various other gadgets on the shelf. I think mine was under $30, not very expensive, but it never gets used anymore either. With larger cones on the 201 I just have the tread stand in front and through the thread guide on the bed. I keep my machines oiled and cleaned, so everything in working. I can see the advantage when working on machines that aren't your own and not everything is kept up.
