good luck
most of the people i know with statler stitchers (the computerized part) do not rent out their set up- or let anyone touch it- since it is as expensive as buying a really nice new car! or a mortgage.
most of the long-arm machines i've seen that time can be rented on are just the machine- with a stitch regulator- if you find someone with a computerized set up offering rent time that would be a person everyone will want to know about!
