I have the dust collection unit that Ringneck Blues manufactures. Does a really nice job, I'm using a 1.5hp cincinnati dust collector. Does a really nice job with wood, using it on corian (lithopanes) it tends to make a mess inside a bit more than wood. I also redirect the exhaust from the cut motor back into the machine just to keep things sturred up allowing the vacuum to suck it up better.
