Not sure who here has seen these, but they're pretty slick. I discovered there's a sale going on at Oneida-air.com and they've got their smallest cyclone on sale for $40 instead of the usual $60. http://store.oneida-air.com/dust-deputy-diy.aspx

I ordered one and when it arrives, I'll set it up on top of a bucket and we can use it with the shop vac for point-of-origin dust collection. Now I just need to build a dust hood for my CNC and I'll be set.

That looks like a really handy tool! I'm excited to see it.
