I was reading about the Pentair Intelliflo that is supposed to reduce energy costs up to 90%. Is that complete overkill for a pool like mine, that doesn't have lots of bells & whistles? I replaced the timer with a simple dual mechanical timer for the pump & sweep last summer - will that have to be replaced again for even a dual-speed pump?

Any guidance appreciated. I'm clueless on this at the moment, but will keep googling for answers...
