O.K. People I know that there are many threads probably on this subject however please humer me! I want to upgrade from my "weedeater brand" to a new Echo or Stihl (only two brands my dealer sells). I only mow 8 residential yards per week and also will be purchasing an Edgit to be installed on said trimmer. I do know that I want to stick with a tap and feed string system. So what model is best, most comfortable, reliable.... Thanks for your thoughts!
