I've tried 3, the first was the Badger Pond shop built one; it was pretty good except for the hanging the thing from the ceiling part...could never figure out how to do that in my shop. Next I went with the Shark Gaurd mega mouth. I should add I've always had a Bies snap in splitter (Unisaw) so the shark was made to clamp right onto that. The Shark is superb, easy to move out of the way and really did a great job on catching the dust. Then I came across a used Excalibur, something I had always wanted and didn't buy because of the price. So I bought and installed the Ex only to find I didn't like it as much as the much cheaper Shark. I still have the Shark and keep threatening to switch back when time allows....it would get my vote for the top choice.
