I actually have an original C8FB. The C8FB2 is even better: self-retracting guard is the best. As you lower the saw, the guard pulls itself up via a linkage. My older model allows the guard to touch the wood and is pushed up by being in contact. Not bad on 90 degree cuts but if the saw is laid sidewise, the guard binds against the blade. They fixed this problem elegantly on the B model.
