Three years ago when i installed my PE Pacific insert. I decided to cut my own wood. To see if was for me. I purchased an Echo CS400 saw. I have to honestly say after three years and @14 cords of wood it has been stellar. Now that I am cutting bigger rounds and have acquired the wood bug. I am thinking of moving up to say a Stihl ms 362 or maybe a 441. To the experts who know. Will my cutting times improve enough to justify the cost? Not to say save my ailing back. Or, should I look at the Stihl midrange line of saws and save a few dollars?
