I only know Felder from afar, but I was curious. And since Felder doesn't really show prices on their website, I asked Google. Evidently, for the K 740 S x-motion with PCS, it will cost about $50,000. Just for S&Giggles, I priced up a 7hp ICS with all the trimmings (including slider - I realize they're not quite the same) for $9,357.
If the SawStop brake costs $119 and the Forrest Woodworker II is $170, and you bought that ICS, you could have 140 activations and blade replacements before the expense will have equaled the K740.
