the company I work for has only ran with stihl multi tools. great machines aside from when it rolls to its side in the back of your truck the gas flows up the carb and soaks the air filter to the point of it being next to impossible to start without opening up the air box. that's the only down side I can think of for the km90. I am opening up my own landscaping company in the spring and I know of an echo pas-265 that is for sale for dirt cheap. are they as well built as the km90s? any good or bad points to the machine I should know about?
