Like Chris said this is a better deal with a warranty. Its $739

I think the XtremepowerUS 40K gallon SWG offered from Home Depot is now changed to a more stand alone cell unit .
Its not a standalone unit, it has the standard pentair power unit plug. The models that come with the power center cost $90- $150 more. So technically its still a savings but with no expected lifespan posted, i would never gamble that much money to try and save $150 over the lifespan of the unit. For all we know its a 2k or 3k hour unit.That a full system with the Power Center or just a replacement cell?
