I was primarily thinking about dust control, not hand protections, seeing how the benefits of a slider is that you move a table verse the piece - but I definately see your points. Now that I see them, I feel foolish.
Erik - I'm still not following the Felder issue with not selling the overhead gaurd. What does price point have to do with it? If I'm a customer willing to buy one, why can't I? Will it not work with the Hammer line? And to clarify, I'm talking about the optional, overhead guard that lists for about $1500 (but currently on sale for roughly $1000).
