I have one and took it to the Bonnie Hunter retreat. It sewed fine the first day, but I never got a stitch out of it on the 2nd day. It did not look disturbed when I came in. Another retreater had one and came over to see what she could do, and she did not get it going either. Something about the bobbin thread keeps getting knarled. I tried changing the needle and it still did not go. The next morning we had 5 inches of snow, so it did not get to the repair guy.
You can have this one in its present condition for $250 plus shipping. I have way too many machines.
