Thinking of converting to a SWG.

As far as I can tell, these are the comparable models for our 20,900 gallon vinyl pool.

Auto Pilot Digital with SC-36 Cell or Hayward Aqua Rite with T-15 Cell.

The Hayward is cheaper and boasts 40k gal instead of 36k on the AutoPilot, but the Autopilot has a built in pump timer. I like the timer idea, since our timer is pretty old & I've shocked myself trying to move the little switches to set the on/off times! Ha!.

Any opinions? Thanks.
