That saw has been around for a while, i've seen it demoed a couple times on TV...
I think i'd rather "nick" my finger than pay the $100.00 for a new cartridge + the cost of a new blade!!! I said NICK not "loose!" But of course after more than 30 years of tablesaw ownership, i still have all of my fingers, so i must be doing something right!!
If i remember right, the saw is in the $1,800.00 bracket, stripped...
