Pool liners for the backyard.

Where can I get pool liners to go into a small wading-pool? My uncle is looking for a site that has things like this but I haven't had too much luck in the search engines. Plastic or fiberglass would be ideal.

Okay I am answering my own question because I did find a place when I looked through the yellow pages under pool supplies that also sold outdoor fountains and furniture. They had catalogs to look at and I was shocked to see how much is out there for pool liners.
