You got it, price, performance and availability in one.
Don't worry to much about GPH capacity as they are only designed to remove bilge collected water and not a moderate to serious leak. They do keep water accumulation from damaging the sole. Get one with enough power to lift the water enough "heads" to propel it out. For redundancy I would consider a dual pump installation in case the primary fails. I hardwire ours directly to the batteries to be able to shut the battery switch without affecting the pumps. A fused (+) lead is necessesary as well as a reliable power source. For safety at sea a manual pump preferably located at the cockpit should be installed. A quick inspection of the bilge is recommended before going out.
