I love my Bosch sander but my Ridgid works better at collecting dust when hooked to the same large shop vac and a dust deputy. I wish the Bosch had the additional cowling that the Ridgid does. I don't do a lot of power sanding but a recent project has had ROS DC on my mind ;-) I do use a mesh abrasive and an interface pad which work pretty well. The Bosch scratch pattern is superior but the Ridgid collects better. I don't qualify for a $1000 ROS solution (although I was happy to buy a Domino). I will percolate on this and see if I end up doing more power sanding as I get older or continue with hand tools. Decisions, decisions.
