For years there was only one brand of machine that had a 'walking foot' built in and that was Pfaff. They called it the 'IDT'. They had the patent on it so no other machine company could use it. Since Pfaff was sold some years ago it has spread. Now there are 2 or 3 machines that have this technology. I can never remember which ones, but I believe Janome is one.
