You can get the Polysodium acrylate beads at Michaels Arts and Crafts stores. A little bag of these beads is less than $2.00.

Thanks for the clarification. Although you setup is more complicated than standard pillows, it sounds more reliable (and cheaper.) If I ever get around to setting up a cooler, this is exactly how I'll do it.
