I've had my Pfaff QE 4.0 for seven months now, and just love it. It does everything I ask of it and then some. Just this week I hemmed a pair of jeans for my father and it went through all those layers of denim like it was sewing through two pieces of quilting cotton. FMQing isn't a problem. There were problems w/ earlier versions of this machine, but those have been corrected. My only complaint is the markings on top meant to help with thread direction for threading --- they are the same color as the body of the machine and are very difficult to see. Other than than, I am pleased as punch.
