Echo gets no respect.
I have six chainsaws of six different brands, including pro saws from both Husqvarna and Stihl, and I love my old Echo 510EVL ("Five-Ten Evil"). It's a little power plant that simply NEVER fails to work.
One local dealer who carries all three told me a lot of folks soured on Echo saws in the late 1990's / early 2000's, when they put out the early CS series saws, which were less than impressive. He said they seem to have righted those wrongs in their recent models, but public perception can take many years to swing back in their favor. Most local dealers and landscapers seem to consider them and Stihl neck and neck on other equipment (trimmers, edgers, blowers, etc.).
