There are tons of places that people can get milking machines. Some of the PE sites are also using parts from milking machines spliced into basic electric vacuum pumping equipment and claiming that it aids in tissue stretch.
Ebay often has milking machines very cheaply and tons of pictures. To have one you need a relatively decent vacuum source, the machine itself, an adjustable "pulsator" and the multi-piece teat cup.
There are tons of references to these in more places than I can count, and I personally would see little difference between this and the average vacuum pumping sessions that are enjoyed by many.
