Be aware there are dozens of variations of Craftsman table saws, 8" and 10", differing table widths and lengths, different rip fences, different motor horsepowers, aluminum and cast iron extension wings. Some are heavier and more valuable than others.
FWIW, the value of older table saws has tanked in my area. Younger guys are terrified of old table saws; seem to feel if one walks near anything which isn't a SawStop, it's likely to roar into action and rip one's arm off. In the past century, I'd buy Craftsmans needing a lot of work for $25-50, , throw in new bearings, belt, motor, pulleys, whatever was needed and sell them for $250. In this century, I've been given similar projects just for hauling them away and then been unable to sell them at a profit after all my work. Today, I don't rebuild them.
Another FWIW, when Craftsman table saws became so cheap here, I bolted together two saws and two extensions to make a huge table and kept one trued for 90-degree cuts. I then added a Delta Unisaw Unifence which someone had junked to install an aftermarket fence. That made a very versatile saw for cheap.
Pro tip - the motor hanging off the rear can torque the trunnions out of alignment. I always added a locking bolt to the rear trunnion to match the one on the front trunnion. To accurately adjust the blade, remove the belt and the motor, so the motor isn't fighting the adjustment, use a square or an angle gauge to set the blade to the angle you want, tighten both trunnion lock bolts and then reinstall the motor and belt.
