I decided to go with the Pentair IntelliFlo VS 3050 High Performance Pump from Amazon for a total of $882 (includes shipping.)
My local pool supply retailer said they would try to match the price but I'm not holding my breath. I'm now shopping for a sand filter. It seems there probably isn't much difference between Pentair, Hayward, and other brands. If anyone has a differing opinon, I'd love to hear it.
