I love the knee lifter on my old Bernina 830, that machine has a million miles on it. The new Pfaff I use the stitches for quilting, making clothes, doing crafts, that's what it was purchased for. I love the way it does buttons holes, a no brainer there and I need all the help now days. I had to purchase the walking foot for the Bernina but the Pfaff came with it built in and it's great. I love the 1/4 inch foot and the stitch-in-the-ditch, I guess I use just about all the features on this machine at one time or another depending on projects.
