Builders almost always think it's "cool" when the property owner spends more money. Just keep in mind that many builders don't even like pools, or have one themselves!

There are situations where a VS pump is a good choice -- but a small simple IG pool in Miami is not one of those. And the additional savings from a VS pump, compared to a well-chosen 2 speed is far too small to justify the $500 price difference, much less the $200 for a surge protector and the reduced service life!
