I haven't "personally" owned an echo trimmer yet. I have used redmax and stihl. I will not buy anymore rm trimmers but they're blowers kick a$$! I like stihl but my fs85r get's weird when the gas tank get's low on fuel. It will shut off and will need to be cold started again. And I have a 4 mix unit kombi and don't like the mixed breed engine that might need valve work and other stuff after awhile. So are echo's anygood??? I want to get one as a test model to see if I want all echos or not. My pb403 keeps running great with no problems after two years. So are they're trimmers good or should I stick with stihl??
