Good find!!
Watching that dude jacking with his head between the bar and the jack gave me the shivers. People don't realize how dangerous the Hi-Lift can be, when not used properly, and that stabilizer foot adds a whole new degree of safety.
When you come to Overland Rally in Vermont (with your new Adrenalin) they have a free class on the Hi-Lift...and I've taken it three times from the same guy..and still would feel better about brushing up on it.
That would be money well spent if you plan on utilizing the jack.
