I would definitely purchase one specifically designed for your machine - the manufacturer of your machine or your local sewing machine repair shop should be able to help. My walking foot was pricey, but I can tell you it's worth twice that for all of the headaches it has saved me if I had tried to use my regular/standard foot. The walking foot moves the quilt sandwich through evenly and helps prevent puckering of the fabric. Once, I started to sew quilting lines and forgot to switch to my walking foot and the stitching turned out to be a hot mess...but nothing a seam ripper couldn't handle. LOL
