I had one made by foxcame with the house and was 19 years old when I bought the house). Lasted 20 years before the liner failed. Was able to get a new liner for $3K. Kinda nice. Pools are a lot of work. Find a good pool place that will help you maintain it (via advice). I wouldn't hire someone to open or close it. Waste of money for what you get. You don't drain them ever. Get a winter cover for it and you will save money on chemicals in the spring. The winter pool cover keeps algae from growing by keeping sunlight out of the water during the winter. You have to be careful not to poke a hole in it while cleaning but it's not a huge danger.

I'd go with an in ground over an above ground any day. And I wouldn't buy a pool again if my life depended on it -- too darn much work. ;-)
