A friend had a contractor saw built into a cart that extended the table. The saw was leveled, the exact height set with shims so the saw table and the surrounding table were level. He'd cut a couple of miter slot extensions into the table top. The stand had lots of storage for accessories and was very heavy and stable. A circ saw with a decent blade and a straight edge for pre cutting to smaller sizes is the cheap solution to handling large sheet goods. Even with help, I just don't want to wrestling 4x8 or 5x5 sheets anymore.
The real issue to me is power. I went for a Laguna 1.75 hp saw and stalling and even burning all but stopped compared to my old 1hp Delta. I can also upgrade it to 220v to add hp if I want, but I haven't needed that much power yet. The Table saw is the center of the shop and it can do so many things for you. Check out the Bosch 4100. They seem to be at reduced prices just now, and there is no question it is top of the line for that category of saw, including having a decent fence and taking a dado set.
The more I do, the less I accomplish.
