Whats your favorite mech. fuel pump?

I've installed several of the AirTec electric pumps in modern vehicles without a problem.
First mechanical pump I bought with the AirTec brand on it was junk. It's mounting flange wasn't flat or square with the pump arm. The female fitting at line out could be cracked from the body waaay too easily.
Best price I found for Carter was at RockAuto.com
