I am in the market for a blower. I notice that the professionals use backpack blowers. I do work on the side and may not NEED the best, but I like to purchase quality equipment that will meet or exceed my expectations and that will last. I realize that backpack blowers are more powerful than a handheld and they may be more comfortable if you are blowing grass clippings for 20 minutes at a time. However for someone like me who would use a blower 2-3 hours a week, is the cost of the backpack worth it over the handheld? What other advantages does the backpack have over the handheld? By the way, I will be purchasing a Stihl.
