Rather than use a big clunky walking foot, I prefer a machine with a built in walking foot, like a Pfaff, Babylock, or Janome. Understand every machine made with these names doesn't have a built in walking foot, but most of the Pfaff machines have it. The Pfaff walking foot fits in a groove underneath most of the feet, so it can be used with most of the specialty feet as well as a straight stitch foot. It's always there, attached, so it can't be lost, and is completely unobtrusive when sewing. It's called the IDT on the Pfaff---it has other names with the other brands. I love it and won't sew without one now. It has completely spoiled me, lol.
