What is the best backpack blower? I'm looking for one to replace the one I had stolen Friday the 13th. The Echo PB403t I had was a good machine but I wonder if I can do better without spending $400.00. I've noticed that Stihl blowers with less air speed sell higher on ebay than Echo. Why would that be? I never had any problems with my Echo ($299) with 180 mph air speed. Some Stihls sell for over $350.00 with 160 mph air speed. I've never owned a Stihl product but at the same time like my Echos. Please help me decide.
