I have the pfaff 4.0 and absolutely love it. I have other machines {Vikings} but much prefer my pfaff for the even feed IDT, that's why I decided to buy it. Wonderful for piecing and quilting and the throat space is almost 10 inches and I have quilted up to a queen size quilt on it. This machine has many wonderful features and the 9mm deco stitches are beautiful! I love mine and would recommend it highly.
