This is my comment too. Unless you are planning to become a professional tailor or home decorator, one of the sewing machines you list as owning should have a hem stitch built into it. Blind hem machines cost a few hundred dollars and do the chain-type stitch as mentioned....and one less " machine" to make room for. Jmho
