After doing a little research and seeing some great reviews, I decided to purchase the ECHO CS-590 20" chainsaw for $399 from Home Depot. I am not affiliated with either co., just want to pass on my experience.
This thing is awesome! I have only used it for a couple of hours so far but it cut through a 20+ inch White Oak like buhdda! I am thinking about getting a 2nd one as a back-up.
What chainsaws do y'all use?
