Howdy! I have a Bosch worm drive, which is a skill 77 exactly, same case. The label says 15 amps, unlike the skill label which says 13, but I think it's the same motors. The bosch has the hook that comes with it, and it's also alot lighter then the 77. It has the same kind of warruntee. The bosch has a really nice base plate, and the blade guard DOES NOT catch on thin material like the Skill 77 does, that's about the only REAL difference that makes a difference on a jobsight, as far as I can see. This is just my experience with the Skill and Bosch worm drive units. Hope it helps a lil. Brian
