After waiting several years to purchase my pool, I'm finally able to do it. I thought I was ready to purchase from The Great Escape. But, after reading dozens of negative reviews I am scared to buy from them. Where is the best place to buy an above ground pool? I should also point out that I want a 21x43 oval pool. I know most people go with round pools, but I'm a swimmer and want the distance for swimming. Thanks for any help.
