I would honestly spring for the metal frame pool over the blow up ring. We have had both, this year we got the bigger one at Sams (metal frame) and we love it!! The set up was a breeze and despite the fact that it is not perfectly level, it has not been a problem. We had the blow up pool before, and it really was so much more trouble. The ground you set it on really has to be close to perfectly level, and if the kids lean on the sides too much or anything like that, it tends to become a problem. We love our pool so much already, and school has not even let out yet!! Have tons of fun, and regardless of which one you pick, once it is set up and situated, you will be happy you have it. (If for no other reason than GW perfectly stated "healthy rear" situation:)
