Bosch system is cheaper in comparison: You have to replace the cartridges (~$156) which can fire twice (so 78 per activation). With SawStop you have to buy both the break ($69) and the saw (15-100? depends on the saw). Prices taken from amazon.com (so I don't know how realistic they are, the cartridge may actually be much cheaper, I don't know where to look at the official price)
