This saw is great. It is alot lighter that the old 77 but with the same awount of power. This saw will cut threw any wood like butter. I particularly never liked worm drive because they are way to heavy but this  saw is a little lighter and feels good when i use it. It feels more like a  15 amp saw than a 13 but you cant go wrong buying this saw, its been around  for decades and they probly all are still working
