A cabinet saw will have much better dust collection than most contractor saws. I agree an overhead guard with dust collection is going to really help capture dust when edge trimming. Comparing the G0691 to a Sawstop is not really comparing apples to apples. Is the SS worth $1500 more??? thats up to you, the SS is more money and should be, you are getting way more than just a brake. Dust collection on either saw will be a major step up from where you are at now.
