Good; I'm glad it clarified things.

A decently sized round Intex is pretty easy to install, and not a huge investment (as pools go). If you are not sure, you might want to put one up, try it, and see how much your family really likes it. If you decide to go bigger . . . or bail out . . . you can probably sell it for 1/3 - 1/2 the original price after 1 year. Be sure to get the sand filter -- cartridge filters work, but are rather unforgiving: once the pool's cloudy it takes FOREVER to clear.
