I'm in need of a 1/4 HP to 1/2 HP submersible utility (NOT sump) pump that is non-automatic.

I need a pump that has a very low minimum operating level for the pump to prime. This isn't the same thing as a pump needing 2 1/4" inches of water to prime and then being able to suck down to 1/8" of water.

I'm already aware of the Little Giant pumps but I'm looking for something less expensive.

Does anyone know of any? I keep looking at websites but almost none list the minimum operating level.
