I was ready to order the Husqvarna top handled battery powered chainsaw after watching the "climbing arborist" youtube channel. Treestuff then said they quit carrying them because they had too many issues with them. Stihl also makes a battery powered climbing saw. I would use it for pruning primarily. Is it worth the investment to buy the saw? (and hedge trimmers?) Which brand is best? Where to buy from? Thanks for the help!
