I had my eye on the 21" 3hp Grizzly. I just didn't want to be "penny-wise, pound-foolish" by not spending another $500 and getting either something better or more powerful.
You know, that a darn good idea. I would have to leave the space behind the BS empty anyhow; I can just stick the TS there as an outfeed table! I already, due to lack of space for anything else, use it as an assembly table and router table.
