I have the Central Machinery OSS. Not a heavy duty unit by any stretch, but I don't put much strain on it anyway, so it functions just fine for me. If your looking at production work, you might want something a little more "high end". I believe this is the same model that used to be sold by Home Depot, but with a Ryobi label on it. Check Steve's videos, it's identical except for the label.
BTW, the July issue of Wood Magazine has a coupon for $89. FYI
