We had one of those before we put in a real pool. Much cheaper than the $60k we spent putting in the real pool :-)
Some pics of the construction. I have pics of the finished project...just haven't uploaded them yet.
I love this pic. I call it "anticipation"
Just make sure the portable pool is on VERY level ground or you will have problems with it. I can't stress this enough....
Also, the wimpy little filter that is included with it doesn't really keep it very clean. Ours always looked like it was filled with swamp water. If you can find a larger filter for it, I would recommend that.
