I have to admit that I'm split on this one. As Tom says, what price do you put on body parts? But as the Intimidator says, I see more and more people doing more stupid stuff because something is supposedly "perfectly safe"...
I've been using power tools since a very early age and was taught a deep respect for them by my father and grandfather. Yes, there have been a few stupid moments over the decades and I'm lucky they didn't cause any lasting damage. At those moments something like the SawStop could have been worth the added insurance. But even those incidents served to teach me well about paying attention to what I was doing, whether I was fatigued, or whether I was doing something just plain stupid.
Sort of like the statistics for driving that say that the safer someone feels in a car the more likely they are to get into minor accidents. The threat of injury can be an excellent way to keep you alert!
