Has anybody in the area tried or have one of the pop up pools?  We are buying a new home and were trying to purchase a pool with it.  But of course the preferred pool builder was way too expensive.  So we are now looking at alternatives.  I've been looking at them on walmart.com and their not too expensive.  Just looking for some local, honest reviews on them.  They seem like a good deal, and would provide for good summer time entertainment for us and our two small children (2 and 5).  Thanks.
