I'm using a Bernina 830 as well and I love the machine. It is a work horse and has been extremely reliable. I have really come to rely on the Bernina brand. I actually had to have the motor replaced a couple of years ago because my grandmother (original owner) hadn't been able to take care of it and lived in AZ where the heat had affected it. My DH fixed the feed dog drop yesterday and now I get to see what more this wonderful machine can do! Wahoo!
