I bought a complete dust cyclone from HD
[Dustopper] for just over forty dollars. Works great and easy to hook up. It comes with the intermediate hose and an elbow. You do need a five gallon bucket available from HD for a few bucks.
I see it went up in price a bit since last year.
Yes, I have the dust stopper too, works well. I have a small tabletop cabinet with glass beads for fine work and a larger cabinet with Black Diamond in it for heavy rust. The glass bead one has 2 halogen lights, the BD one has LED strip. I agree, the more light the better!
