most people don't know this but the old table saws were made in paris, tn. emerson electric ownes the division that is or was at least called their SPECIAL PRODUCTS DIVISION headquartered in st. louis,mo. my now deceased good friend VIC KLUESNER was very high up in that division. i went to paris tennessee and toured the factory. the specs on these saws were extremely tight. back in about 1998 they lost the bid from sears to ryobi and no longer made for sears. they got the contract with HOME DEPOT and are now sold there. they rebadged them as RIGID since emerson electric also owned rigid.
if it were me i would keep your own saw and look for another old sears for parts. you could always upgrade the electric motor. its an interesting story that my friend lived because he had all kinds of in sites about sears because he traveled with all the reps that sold their products as sears own.
