Klippermate is a great deal
I have strung 4 racquets and found the Klippermate easy to use and comes with instructions and string patterns. Definitely recommend it for home use. Floating clamps work great. Poly is a little tough to string, but I managed and after a few times I'm sure it will be much faster.
