You'll be pleased. Ive never owned a 170 but did have a 180 years ago. It was a heck of a saw for the price. I cant remember exactly why I got rid of it unless it was to upgrade to larger saw.I appreciate all the replies. Ended up going with a Stihl 170. I'm sure the Echo would've been good but the Stihl was 2" longer and $20 cheaper. Thanks again!
