I went to sears today to pick up a pole pruner to limb some trees around the house, when it warms up. Saw a 18inch chain saw on the close out rack for $60 well I could not pass it up. At the store thought the blade and chain seemed small when I got home and compared it to my stihl 390 could not believe the difference. The stihl has a 20inch blade but the chain was almost twice as thick. Anyway not complaining just surprised by the size difference, will see how it cuts this spring.
