My Sear Kenmore is made by Janome.
I bought a "quilting attachment set" at the Sears store that was $26. You got walking foot, 1/4 inch seam foot, darning foot and cloth guide in the box. That's the best price I've found. If you have a Sears that sells sewing machines, it's worth a look. Be sure to take some feet from your machine to compare.
