I have narrowed my choices down some, if anyone could give me some opinions on these.

Pentair 011512 WhisperFlo - more expensive, but heard really good things

Pentair 340037 SuperFlo - Not eligible for prime shipping, heard good things, cheaper.

Hayward SP2705X7EE - can't find much information on it, prime eligible.

Any opinions would be greatly appreciated.

Thanks,
Jesse
