I had no considered 2-speeds. Are there advantages to a VS pump vs 2-speed pump? Additional savings?
What about the warranty for owner installed vs 'professional' ? In particular the Pentair is 60-days vs 1+ years?

Re: Old Motor Seized Need New Pump
The savings from a 2 speed pump is HUGE. In typical installations, on LO, the pump moves about 1/3 of the water with 1/10 of the electricity (3x increase in efficiency) Also, filters function better with LOW flow, than with HIGH.
VS pumps save a little more, but are more expensive, more complex, and usually work best with electronic pool controls . . . which are ANOTHER point of failure. I'm not a huge fan, for simple pools.
