The price difference isn't $80. My Grizzly cabinet saw retails for around $1100 today. The equivalent Sawstop saw retails for over $3000. When he couldn't convince other manufactures to include his technology, he built a high-end saw to market himself. That still puts the extra safety out of range for us lower-end consumers.

And the danger with table saws isn't carelessly putting your finger into the blade. The danger is kickback, where the saw violently throws the wood your cutting off the table, which can knock your hands about in unpredictable ways. Bandsaws and miter saws don't kick back. You can safely put your fingers very close to the blade (although a little less so with miter saws which do tend to push the wood around a bit as the blade enters the wood).

Of course, I wish I could afford one of his saws. I once put all four fingers of my left hand into a dado blade on my table saw due to kickback. I'm lucky to still have them.
