You're lucky to have found someone honest enough to fix the machine right. Hold on to them; they are a dying breed. Took mine 70 miles to the dealer to fix, got it home a week later, tried to sew on it, and still not right. So, electronic machine or not, I took a screwdriver and opened her up, vacuumed all the gunk out, put in a couple drops of s.m. oil and closed her up. Runs like new. No more 70 mile trips; although there are a couple of nice quilt shops down there!
