I would have to agree with the Clockman that the old Delta contractor saw has been a beast for me over the past 25 years cutting so many melamine sheets I don't even want to think about. As with many Delta parts though, just about impossible to find. So scratch a used Delta contractor. Yes, safety features are important. But the greatest safety feature (and this goes for all tools basically) is a razor sharp blade, especially on a table saw whether contractor, Hybrid, or cabinet. Good luck in your search.
