do a google search for "big splash center"







Apparently available for about 70 dollars US...plus there are lots on eBay....and plus I saw one in my neighbors yard so they must be available readily...

just a thought - for the price they seem pretty viable given their size. Thickness is pretty good as well.

surely your neighbours wouldn't miss theirs

We have some that are smaller, lighter made and much cheaper. They would do well for a starter, but probably wouldn't last very long. WalMart and most of the other large retailers carry them for under $20. The only problem is most of them are round and because they are real light material will require some sort of support material like sheets of plywood if you wanted them elevated. A friend of mine used one for many years as an inground gold fish pond. The best part is they usually only 8 inches deep.
