I like pool filter sand, which is also cheap. I paid $5.99 for 50 lb bag at a local pool store. Here's how mine look like - http://www.aquariacentral.com/forums/showthread.php?t=158192
I heard that play sand is much lighter and harder to maintain as it gets your tank cloudy if disturbed. I use pool filter sand in a few of my tanks, and never had a problem. I regularly move decor & plants around with no issues at all. As with all substrate, make sure you wash it well at the beginning.
Good luck!
