I second what is above. I just motorized my 7' dish yesterday using vbox-x, sprinkler timer cable, and the PMA24 actuator from WSI. For some reason the SV360 receiver sees west as east and vice versa regardless of what I do, but otherwise I am extremely happy with this setup with a little over a 100' run. The whole process took about an hour including mounting the actuator, running the wire (on the surface for now), hooking up to the vbox, and testing.
Now to get the 6' dish from WSI assembled so I can do it all over again for the kid's room. ;-)
