I'm another happy Tin Lizzie 18 owner! Bought new 4.5 years ago, with a stitch regulator, not computerized. I quilt for me and local charities. I started in a small sewing room with it set up at 5 feet for baby/lap quilts. Now have it at 10 feet and can quilt a queen if I needed to. Never needed service, no problems I can't figure out (operator errors!), and very well-spent $6000!
