I consider the walking foot the second most important piece of quilting equipment I have, after my DSM. So I think the best, brand name walking foot for my machine is money well spent. There are many prior posts on this Board about folks having problems with generic walking feet and that they don't last long at all---had to be replaced and spent more in the long run than if they had purchased a brand name foot to begin with. It is a long term investment IMHO.
