I have 14 stihl hand helds working without a problem and always starting on 1st or 2nd pull. I have a garbage can with 2 echo trimmers and 1 echo blower. The echos were fine when I (owner) was operating them. I am in office more and they just won't hold up to the abuse my morons, I mean employees, dish out to the equipment. Nothing stands up to my moron's, I mean employees, abuse except Stihls. If you treat them decent I expect they are all reasonable good. I have the echo PT-770 blower. It cost me $97 dollars for tune-up and repair after 1st year. They did replace the harness under warrantee.
I think this kind of gives you an idea.
