I was getting ready to pull the trigger on a new Echo 490 then a friend tells me he will sell me his Stihl 028 for $100 less than the new Echo. I want advise as to which one, not both to buy? I do have both Echo and Stihl dealers locally, although I have done my own maintenance and repairs on my 025. I will be using this saw to drop and buck good size shagbark hickories, locust and oak. Tell me please which saw.
