My outfeed table folds, but is usable for light projects. I would rather have one like yours, nice and heavy with hold-downs. My fold down table has 1x3 trussing underneath so it's solid, and two legs that fold down and are adjustable for height. I used part of a Rockler hardware kit to attach hold the other side to the saw, which allows me to remove the table if I need to. I have my compressor on a small platform under the outfeed table--floor space is precious in my shop.
The more I do, the less I accomplish.
