I have the Delta BOSS, and it is ok. At the show in Chantilly they had the Ridgid out and I liked it a lot. The fact that you can use a belt and make it oscillating is a plus. Tilting table, good vacuum hookup, and it seemed like a very well built and sturdy unit. I saw the review in FWW of it originally and thought it was a toy, but after seeing it, it is a nicely built machine.
