My 830 had so many parts and sensors replaced in the first year that I was about ready to throw it out a window. It had to be sent to Bernina HQ and took a month to get back. Still not fixed! Luckily my local tech was able to get the bugs worked out and then the embroidery mother board died. It's now a great machine 2 years later, but for the price paid I should not have had to deal with a product that had so many issues and needing so many parts. I want to scream at all the people who claim it's user error and to take a class to know your machine better. Having a machine full of faulty sensors and needing about 20 trips to a dealer for repairs is not user error. LOL. Now, I'm happy with it but if I had to do it all again I would not buy the machine.
