You're not required to purchase them if you don't want to. Personally, I have a stopsaw. It has never triggered, so beyond initial purchase price, it hasn't cost me a cent extra, but in the unlikely case where I do something dumb or have an accident, I feel better knowing it won't be life altering and all I'll need to do is replace a blade and a $99 cartridge. That's worth it to me.

likewise, but also worth noting that the saw stop saw is just a...nice saw. Better than the old delta I used to have, better than the powermatic 66 that I grew up using. Probably not as nice as my buddy's $20k sliding Felder saw, but...for the price, a Sawstop is a nice tool and highly competitive in build quality.
