Never owned one and more than likely wont use it much. My father wants me to trim a few trees for him so i figured Id pick one up. Should i just buy an electric pole saw for trimming his red tips? Maybe 4 inch branches? Are electric saws worth a darn? Second, If u steer me to a gas the echos start @ $199. I have other echo equpment so it would be nice because of the 50:1 mix. However the other brands are 40:1 and $100 bucks cheaper for something I may use 1/2 dozen times. What would happen if i put my 50:1 mix that I have for my echo equipment in a 40:1 chainsaw? Foul it up? Trying to avoid another gas can with another mix!
