I use the walking foot that came with my Brother all the time with a generic quilting guide (and use the same foot on my Baby Lock and Kenmore but it won't fit the Pfaff). If you do buy a walking foot, check to see if it has a hole on the back to accept the guide. Yes, because of those feed dogs on the walking foot, you can't use it for anything but straight stitching. Maybe gentle curves, but I've never tried.
