my lesco dealer has a kawasaki hedge trimmer for a real good price. I will only be using it 2-3 times a year and was wondering if i should buy it or get an electric one. I know the gas one will be more powerful and i wont have to worry about cords but i dont want it to get ruined form sitting for long periods when its not in use. Also is there anything i can do to the gas power hedge trimmer after use so it wont get all gummed up?? and messed up??
