I had a Kenmore machine that was a workhorse for over 15 years until I finally burned the motor out - too much quilting, but boy did that machine love to quilt and sew heavier fabric. I upgraded because I thought I would get a better machine -nope, I bought a Singer from my sewing machine dealer that barely lasted 2 -3 years, then I just traded up to my Janome 4000, which I love.
