I have a 20 year old Delta contractor with the long uni-fence. Cuts as nice as the Powermatic another local has. I used to do a lot of cabinet making and reproduction work. I took the basic saw and built a roller with dust box base and extended table.
I don't know if Delta has cheaped out on the Contractor but at the time it was a good saw and a very good saw for the money considering the Uni-fence.
The fence is critical in a table saw. You need to have a fence that slides smoothly and stays true without having to be dithered with. I have not seen this aspect in the old Crafsman saws. I had a Craftsman from the 40s and one from the 70s prior to getting the Delta.
Look for a top notch fence, a stable blade carrier and bearings. A smooth running and vibration free blade when running. A blade can get a vibration or wobble that changes as you feed the wood through. The blade will run true when you are loading the wood into it but as the feed rates change the blade kerf changes too.

This makes for wavy cuts or blade marks in the cut. The blade song should be low and steady and sound like air rather than a singing or ringing. A blade that warbles is out of true and the saw needs to be tuned. A good table saw is the foundation of a wood working shop. I sold off most of my cabinetry tooling but will never part with the table saw.
