There's no reason it has to add that kind of cost to a table saw. There's
nothing in it that costs that much. Granted, it's a capitalist world and
the owner of the idea is entitled to charge what the market will bear, but
there's no reason for it to double or triple the cost of a low end saw.

Here is a direct quote from the FAQ page ont he sawstop website;
http://www.sawstop.com/faq.htm#1

How much will a saw with the SawStop system cost?
We estimate that the retail price of a contractors saw will increase by
approximately $50-100 after a manufacturer retools to add the SawStop system
as original equipment.
