the more expensive one is a set.
if you bought separate feet for each of the sizes and functions i expect they'd add up to more than $70.
it looks like it might be a practical choice for somebody who does garment sewing, too.
otherwise, one of the two "just binding" feet makes more sense.
i wonder two things:
(1) how hard is it to use them on a quilt sandwich; and
(2) how would you go around a corner?
