Congratulations! I have had the D1 on my hands twice. The first time I was helping a friend set hers up, and the machine broke right there. It wouldn't sew. The store found out it had a defect and exchanged it. On another instance I got one as a loaner while my Bernina was being serviced, and it was broken too. The bobbin winder was engaged all the time. Is a great machine, but better if used for embroidery only.
Enjoy the new machine.
