I live in Canada & have had the 820 for almost a year. I was scared to death of it at first & wanted to return it to the dealer. Luckily she made the effort to help me feel comfortable with the machine & boy I am NOT sorry. The problem I had with it was the bobbin. It is so different from anything I had in the past it scared me. I now do regular sewing, quilting & with the 12" throat quilts are easier to move around (not perfect) but easier. Make sure you clean out the bobbin area often & close the bobbin door slowly & things should be alright. You can have problems with anything so you can't always be sure but I LOVE my machine, now that I gave it a (learning) chance.
