I had a jobsite that I started out with, and almost 5 years ago, I bought a 113 series craftsman contractor saw from craigslist (cast iron top, induction belt drive motor), and paid about $100 for it. I put another $200 into with a fence and other updates. It has been a proven machine for me.
Where did I say I hate Saw Stop? I happen to really like Bosch tools, as well as think the competition against Saw Stop will do nothing but benefit the consumer in the long run. As for unproven, was Saw Stop a "proven" cabinet saw when it was first released? Based on my own experience with Bosch tools I would feel safe buying a machine from them, and has nothing to do with hating the competitor.
For what its worth, I am not even at the point were I can seriously consider replacing my table saw. However, I have looked closely at the Saw Stop machines, and find them to be one of the best table saws on the market.
