Pfaff Performance 5.2; nice wide throat, great design stitches in all categories, including stacking stitches in this newer model 5.2, and Pfaff's patented IDT, a builtin walking foot on back of tension bar, there for your convenience. Would not have to buy separate walking foot. I have the Pfaff Performance 5.0 on which I quilted a queen size pineapple square quilt, using SID, Design stitches, and some FMQ.
