Anybody have one of these? After 8 hours with a pretty powerful backpack blower I'm starting to think I could justify using one of these 2-4 times per year. I just tried a friends 5hp and it was marginally better than the backpack blower I own. I'm thinking I have to go bigger, like get engine big so I can just point it at the trees and knock the leaves right off the trees so I don't have to wait. My budget is $500 (sold some junk) and would like to stretch it by buying a used commercial unit. Little Wonder seems pretty popular if you can get 'em. Is this just a piece of equipment I'm going to regret, or am I going to tear up and cry about all the wasted years I never had one?
