I really like the 670, a little on the heavy side, but for a bigger saw, it works great. I do my own sharpening and with a fresh chain it makes quick work of the big stuff. My saw of choice is the 510 (520 now), lightweight, and lots of power. I am sure you will have good luck with Echo equipment,,,, in my arsenal is 5 (2otherbrand) chain saws, 2 weed eaters and a leaf blower, all of which I have no complaints. Still running a early 90's 452, makes a good backup saw, if I would ever need it. /forums/images/graemlins/grin.gif
