I am wondering if anyone has had any experience with a self propelled leaf blower? Local dealer has one from Giant Vac, a 16 horsepower electric start hydro drive. It sure looks big and heavy. Is the extra weight, power worth about the 1 thousand dollar price tag? Giant Vac no longer makes this unit and the dealer wants to get rid of them. They were selling for $2700 when they first came out. I appreciate anyone who has experience with this beast letting me know.
