Hi, I am in the process of building a home and want to purchase a Michael Phelps Impact swim spa. I have been searching the net trying to find the retail price of the spa, to no avail. Someone posted a price that said $40, $50 (I assume thousands) but that doesn't help me evaluate a quote I have for purchase/install of a spa. Has anyone tried to find the retail prices of the MP spas? If so can you post a reply with a link? Thanks
