I am trying to decide what blower to get. It will be used for Fall leaf cleanup. I picked up one of the $299 413 Echo that HD sells and it doesn't have enough power. I am looking at the Tanaka 7600. Would I be better off in that class or should I just spend the extra money and get a Tanaka 7800 or Red Max 8001? I haven't tested either one yet but spec wise those are what I am looking at. How big of a power difference would I get for the about $100 difference in price between the two classes?
