I saw a youtube video comparing the Dust Deputy and the Home Depot Dustopper. I went with the Dustopper for 40 dollars. Thirty minutes after getting home I had set up the Dustopper with a 25-year-old Craftsman vac, a 50-year-old car creeper, and a milk bottle plastic bin. I was in business.
Works great, Almost nothing gets through to my vac. It's so successful that I'm going to get more for each work station and find used shop vacs for 25 bucks or less. Even new shop vacs can be purchased for 50 bucks on sale.
To me it's cheaper and so much easier to set-up and use than a huge shop-wide dust collector system. If I had one for each tool (table saw, router, band saw, drill press) I still come out cheaper and just as effective in my opinion.
I also use these to clamp hoses onto dust ports. Zip ties w/a quick release. I picked up two more today. About 3 bucks each at HD.
