I have the Pfaff Expressions 4.0 which is just below the big embroidery machines. I bought this one because I would never ever use the embroidery of the next one up. I also have a 7550 at our mountain retreat, which was my second Pfaff. I love the built in walking foot. I hate the big clunky ones of other machines. I have a knee lift with mine but don't use it at all. Jan
