Im going to buy a backpack blower in the morning. Looking at the Stihl BR350. The BR200 is cheaper. Is the cost of the 350 worth the expense? Im using to clear leaves from two giant pin oaks. These things are huge, probably planted when the house was built in 1956 and its almost three acres. Any suggestions on other blowers welcome. I have a bad back, neck, shoulder and elbow so the backpack just makes better since to me. Im trying to keep it under $400. Sorry for the short notice. Thanks. Jason.
