I just ordered a Stihl FS 100 RX trimmer from local dealer and wanted to get a Stihl backpack blower too but did not realize the cost, the low end ones run 300-400$. For a part-timer with 20-25 accounts, would buying a used commercial one or new Husquavarna high end res. unit(179$) hold up for clearing driveways and walkways and the occaisional leaf cleanup. Or should I drop the 4 bills on the Stihl. Thanks for any input.
