Don't get the newly released TSG-FDC Floating Overarm Dust Collection Guard. Unlike the dust collection blade guard and overarm dust collection, you have to move the bulky/heavy floating arm when you make cuts for different thickness of stock or different width of stock. It is a pain and the dust collection effectiveness is not as good as the other option. I don' know why SawStop re-introduce this type of dust collection seen used before SawStop was even invented. $400, I think.
