Hi Matt;

If you want to swim this summer . . . you want an Intex. They actually do quite well IF you stay on top of the maintenance. And, you can go ahead and get a better pump and filter, that will serve you well if and when you go with a more standard AG pool.

With an Intex, you can order it today, and have it running by the end of next week. With a conventional AG, it would take longer than that to buy the thing. You may have to level the ground, but I'm assuming that won't be an issue for you

Intex pools (at Amazon):
Intex 54979EG 24-Foot by 12-Foot by 52-Inch Rectangular Ultra Frame Pool
Intex 56416EG 18-Feet by 42-Inch Easy Set Pool Set
Intex 54955EG 18-Foot by 52-Inch Ultra Frame Pool Set
Intex 54949EG 24-Foot by 52-Inch Metal Frame Pool Set
If you want something smaller, Walmart may have some good deals.

If you are OK with a sand filter, this combo at Amazon seems to be on clearance, and would work well with a pool up to about 17,000 gallons. Since it's a 2 speed, it would save you a LOT on electricity:
Hayward SP15922S Power-Flo Matrix Above-Ground Pump 2-Speed
Hayward Pro Series Top-Mount Pool Sand Filter
