This post is on behalf of my wife, who posted a similar question on another forum and received zero replies:
"I'm a newbie and want to buy a Reallyezpool , the 7'x12' for lap swimming (with a harness). I have yet to see anything about this above-ground-pool on any forums . We used to have a spa for my husband's back issues, it was hard to maintain, and he hardly ever used it. This has made him skeptical about my motivation to maintain a pool given the $1500 price. We have a very narrow lot too and anything wider than 7' would encroach our walkway. Comments and ideas about good quality brands and/or sellers would be helpful. Thanks."
I noticed this site is much more active and hope we might receive some helpful advice.
