I know another question I need a good backpack blower with a lot of power ! I have a great Stihl dealer but Stihl is lacking in that department! I have a dealer who I am going to be buying Mowers from 65 miles away! He has both Echo and Red Max ! He said He sells about 50/50 on the Highpower backpacks! Echo PB 650 and Red Max EB 7000 which should I get ? The Red Max has more power, a larger air cleaner, and is 3.3 pounds lighter. The Echo has a 2 year commercial warrenty I am thinking Echo ! What do you think ?
