I have a Bernina 630e that I bought on e-bay not quite three years ago. It came in perfect running condition with very little time on the sewing and no embroidery time. It came with the BSR foot. It has been an absolutely wonderful sewing machine. When I first won it, I was scared to death!!! I had no idea what condition it would be in or anything. No, I don't have a warranty, It has had 3 cleanings (I have a lot of mileage on there now) each time it ran about $85 and they also updated the software each cleaning.
What I am not happy with is the embroidery software that I got with it is old (which buying used, duh!) (editor lite ver 4) and it was too out of date to be able to take a class to learn how to use it. I have not figured it out yet. Wish I had someone to just show me!!! I have used the em unit for my quilt labels but hope to someday figure out how to do more
