We've got one that I picked up before the craze several years ago. Nothing special, just an 8' tank with a sand filter setup that a friend gave me. I'm into it around $500 including the cantilever umbrella I bolted to the slab. Have little kids, and they love it and use the hell out of it. I jump in on occasion to cool off after a workout or after working in the yard. I'd rather have an in-ground, but that's not meant to be at our current place.
