Is it strictly necessary to have an insurance or some sort, being a carpenter / mason?

I have a question for carpenters. Share please your opinion about worm drive saw, is it easy to use with one hand? I am thinking of buying Makita 5007F 7-1/4-Inch Circular Saw. Is it heavy, well balanced etc? Can you compare it with sidewinder? I am using it now. Or you would recommend both for different types of work?
