I hate leaf blowers too. In fact, I have railed against them on this forum before (I can't find the post, however, but I remember catesta coming to their defense, which makes sense considering his line of work).
However, I must admit that I bought a combination leaf blower / vac / mulcher. It's much quieter than my neighbors annoying one and judging by how long it takes her to blow off her sidewalk, much more powerful, too. And it's electric.
I bought it because we have a hedge along the alley that is impossible to rake underneath and a large patch of small rocks for drainage on the other side of the house that is impossible to rake leaves from as well. I'm not one of those people that spends hours blowing my sidewalk or driveway, though, until every speck of dust is gone. That drives me up the wall.
