When my reliable Elna was in the shop (not being reliable enough), I bought a Brother machine from Walmart for under $300. It has lots of feet, including a walking foot, and works pretty well. It's small and portable because it's all plastic. I wouldn't want to rely on it as my main machine, but it got me through the whole summer working on Dear Jane and a paper piecing project when my sewing room was taken over by a guest.
