Hi Deb
I made my own

,, I took a plastic flower pot, put in a 2 1/2" plastic fitting and screwed to the base under the saw,, now it works like a clone vac system and sucks about 95% of the dust from the saw..I use a big vac systems but with a 2 1/2" hose going to the saw.
I had some pictures but can't find them on the HD

but it's a easy one to make and a cheap fix.. the flower pot is one that has a top ring about 16" in diam...a 5.oo dollar item at just about any garden shop..little black paint and you would think it came with the saw..
