Charles,
If you're not committed to a table that is there all the time, you might want to take a look at the fold-down one they did in the February 2009 edition of Woodworker's Journal magazine. It is designed to be permanently attached to a cabinet saw such as yours. If you'd like, I will copy the article and send it to you.
If yours is a small shop (aren't they all?) there is great value in being able to knock down the outfeed table when not in use. On the other hand, if it is permanent, you can use the space below for storage or as Julian suggests use it as a router table, etc.
