Anyone have recommendations for replacing the water pump? Or is OEM the best option?

I went with the Stewart EMP pump. It's better designed than OEM.

Here's a link to the Stewart EMP water pump on ADTR.net.

Had OEM, ran fine. Installed a Meziere, went a few thousand and failed when water got into the bearings. Fought with them to get a replacement, it went a few thousand then water got into the bearings, again. Pulled it and dropped it into the trash, $450 down the drain. Reinstalled the OEM pump, has run fine ever since. I still have all the wiring harness and pigtails tucked away with ziploc ties just in case I ever go back to electric, but doubt I will ever use anything but the OEM pump again.

Edited: That Stewart EMP pump looks nice, and reasonably priced, and apparently higher output than OEM...?
