My favorite hopping foot for all my low shank machines is a little $3 cheapie. I have at least 8-10 different hopping feet and this one beats the others all hollow - very smooth, lots of visibility:

I bought a bunch of extras because I figured that being that cheap, they were going to break - but I haven't broken one in five years of quilting.
