I have to stick my nose in here because something happened that never happened before.  I am not using a skill 77 any more, or even the Porter Cable 743.  In fact I switched from a left bladed worm to a right blader  just to get the toughness and power that this Milwaukee saw has.  The first  guy to review this saw (conceptbydesign) hit the nail on the head when he  said this saw was tough.  There are many well-designed features on this saw  but the best thing is the power and toughness.
