we've decided to put an 18x9x52 pool in our backyard to accommodate four active grandchildren. Planning to buy from Home Depot since we have a special offer with them right now. The 18 x 9 rectangular size is perfect for us and I was almost ready to order the Intex. Then my wife went to review and noticed the Polygroup Pro Series. Basically, same specs except the Polygroup has a skimmer and is about $60 less ($840 vs. $899). It's expensive for us anyway we look at it. However, as I've looked at reviews, I find some people who say Polygroup is junk, and others who say Intex uses weaker steel. What should we believe, and does it really make a difference? Would appreciate any objective guidance as soon as possible. Oh, and I'll definitely prepare the ground well--I got that message loud and clear from the forum. Many thanks in advance.
