I have no personal experience with either the Rigid or the Grizzly - both look quite decent. The Delta, however, I can say has a decent stock fence and lots of parts available for cheap, and was US made, which may or may not matter to you, but always curries favor with me. I know folks who worked at Delta's shops in MS and TN, so that also brings bias.In the end, it's a contractor saw. It can be made to be quite accurate as long as the two rods weren't twisted by a previous owner. It is a lot cheaper than a cabinet saw, and probably more easily resold. My delta contractor sold on the day I listed it, with no pictures. Buy the one you can afford that feels right at the time, sems to be straight (use it before buying), and is available at the right price. All three brands are good.
Courtesy is as much a mark of a gentleman as courage.
