I would write Napa off. Get a Ford Motorcraft pump (they changed the impeller material, so they should be better now). Carparts.com sells them at a reasonable price if you can't find one at your dealer.
Also, make sure there are no left over plastic pieces in the cooling system from the original water pump impeller failure. A nice cooling system flush would be a good thing.
