A year or so ago I got a Delta DC at Lowes for 1/2 Off, as it was too big to keep in their tool department. I was basically brand new. I have been wanting an air filtration system to supplement the DC in keeping my shop as clean as is possible, considering I am making sawdust... My chance came up with a sale at Rockler, so I picked up the JET AFS1000B. I think it will work well in my small shop.

The Jet gets good reviews, and I got the updated unit...more air and still quiet.
