I have a Juki MO-645DE for at least 10 years. It's a real work horse. My first one was a Pfaff and would not have another one, my mother almost threw her Viking down the stairs as it was always giving her trouble. She has a New Home and loves it. When you go to purchase, take scraps of the type of fabric you will be sewing with you so that you can test for your needs, not the needs of the shop. They use only stiff easy to sew fabric for testing so that everything looks good. Have fun and good luck.
