This machine will purr like a kitten for many more years if you keep it clean. My 830 was a dream machine. I gave it to my sister when hubby complained about how many berninas I had. And my sis had been hinting for years. It was such a good machine.
I had every foot for it. That is key. Buy the ones you can get your hands on. They work like a dream for all those extra little jobs you need to do. Ebay has them. I suggest you buy real parts, I don't recommend the others.
