$200 is excessive for the OE water pump, they are available for less than that. Better, just go onto RockAuto Auto Parts
and get one of their better quality pumps which does not include the pure junk (my personal opinion) Cardone brand. Even AC-Delco's water pump which is a very good brand is only $64.79 there.
In my personal opinion, Autozone's (Kragen, Pep Boys, etc.) store brand is, despite its lifetime warranty, junk. Who cares if it has a lifetime warranty when it fails prematurely, especially on the trail. Their lifetime warranty is no indication of its quality, they just assume few will own their vehicles long enough after replacing the water pump to need another water pump so their warranty is really just a marketing ploy.
