I went through about a dozen used domestic machines before I found the Singer U20. I burned out motors, ruined raceways and hooks etc. I even had to have the first motor on the U20 (40 years ago) replaced. One is set up for straight stitch and one for satin stitch. Easy to clean and maintain but do need specific needles which last a long time. The satin stitch is to die for! and the machine cast $1000 back when and about the same now.
