They handle sawdust ok up to a point but as you know it does get in there eventually. Anything you can do to keep them out of the firing line helps which is why I put them under the table out of the way rather than stuck on the sides. The "L" shaped gantry puts the screw at the rear again out of the way.
It's a simple proven design that doesn't require fancy guards or bellows etc and does a good job of protecting screws.
