My question is why are some water pumps advertised for $400 with composite impellers and there are some with metal impellers for 90 bucks ??
I could understand a 15% difference in price but not 300%

That's easy: You will replace the metal impeller units several times before you replace the OEM pump once. Metal impeller pumps also can be devastating to the engine cases when they start to wobble with wear. Do a search, been covered several times.
