We installed one last year also. It was quite easy. I do have a tip about the corners, but I'll have to ask my husband how I should word it so you get what I mean.

We got ours from pool1.com. It was only about $9 more than the cheapest site, but I wanted to be sure and buy it from a place that took returns in case I hadn't measured correctly.

I'll see if I can get a picture and explain what we'd do different in the corners.
