I'm toying with the idea of buying a table saw (my first one) and have been looking at old used ones. Your money seems like it can go very far in the used market. However, many of these saws are pretty old and don't have riving knives and possibly other safety features. I'm looking in the $500 range. In terms of pure safety (not performance) and of course proper usage, are newer saws any safer? Short of push sticks, it doesn't seem like there's an aftermarket for safety features to add to an old saw. You're committed to the original design. If I go with a current model I certainly lose performance per dollar but do I gain in safety? One used example is a Makita 2708. Thanks for any insight.
