This is how I came about this pump....
Wanting to lower my electrical bill I started studying "variable speed" lititures from Hayward and Pentair and what the California "Title 20" is about and 2 speed pumps and hydrolic dynamics and so on. What I found is you can lower your flow and electric bill by using a smaller pump and up your run time. this will still turn your pool the same number of times per day as now (if you calculate the pump run time correctly) BUT because I have lowered the total head by cutting the flow in half this also cuts the resistance in the pipes by 4. Pretty cool, so I did alot of digging after see the variable speed pumps are $1000-$1500 and the 2speeds were only 150 bucks cheaper, and a name brand 1 hp pump would be at least $400 bucks
Hmmm i have a pentair whisper flow WF-6 1.5HP Service factor is 1.47, that takes 22 amps @240v (11A per phase) to run and needs to run 3.7 hrs to turn my pool over. So i dug for a deal on a good pump, This is what I found and bought from fleabay hehe.

It is a Neiko Tools USA 1 HP Pool Pump with strainer basket and boy am I happy with it! I paid 109.99 plus FREE shipping, I paid for it at 4pm and it was delivered the next day and this thing's worth every penny. Its quiet, only Half as loud as my whisperflow and the current draw is less than half my old pump. It WILL prime from empty return pipes just fill the basket with water. here are the specs:
•Inlet & Outlet Thread: 1-1/2"
•Liquid Temperature: 140 Degrees
•1 HP Motor, 3450 rpm
•3960 GPH Capacity
•Corrosion resistant housing
•Clear filter cover lets you see when full
•Max Flow: 220 liters/min. = 58 gallon per min.
Max Head height: 16m = 52ft.
Max suction L. 9m = 29ft.
•Built in strainer filter
•Thermal overload protection
Rear high flow fan to activly cool heat sinks (blows really well)
•6 ft. 3-prong heavy black Cord
Running test using a Kill A Watts EZ (Home Depot 24.99, great price!)
VoltAmps (VA): 954
Power Factor (PF): .91
my clean Purex/Triton FNS48 DE filter reads approx. 7psi. The flow at each of the 5 pool returns feels good.
If you want a great pump on a budget this is it. There unfortunatly was no flow curve printed in the specs. If I can calculate them I will publish them. I will be posting my pics of my project that is currently underway shortly. Basically I plumbed the new pump in parralel with the old one and added ball valves to each pumps output, a switch controls which pump gets power from the timer. The Neiko is used for daily filtration, the whisperflow is only used for manual cleaning because of its extra grunt. I just open the appropiate valve for the pump I wish to use and flip the switch to run that pump. I'm also adding check valves that the Pool Builder skipped! because my equip. slab is at least 60ft from the 32x17ft. IG pool and elevated 6 ft. above the water line.
