Looking to purchase a pole saw for cutting low limbs on trees. Am leaning toward the Stihl gas powered residential unit as I have always had great luck with Stihl products. The dealer is pushing the new battery powered saw. It is about the same price as the gas unit if not more. Wondering if anyone has had experience with these battery powered saws. They told me that Stihl is now putting all their R & D into Battery systems now.
