I'm in the market for a leaf blower and I'm not sure which route I want to take. It will be used for normal leaf blowing activities (blow off drive way after mowing, blow out gutters, etc). One thing that's important is that my wife is able to use it so I've kind thought about getting one of those battery powered ones. Does anybody have any experience with those? I like the idea of not having another gas motor to take care of but I don't want to be buying new batteries for the thing once every couple of years either. I want to make sure it has the power to do what I need.
