Let the bashing begin. I've read so much bashing of different brands on this site I really don't know what blower is the best buy. I had a Stihl br400 that had two coils go bad, but otherwise gave very good service. I have never had any engine have a coil go bad on anything else I have ever owned. That's why I decided to switch brands. Anyone getting good service out of the 8510. I know---br600. I have read just as many bad things about the Stihl as I have the Shin.
