I need non-silica based sand.. help?

I'm looking for a non-silica based play sand - preferably white in color. There used to be a company called SouthDown that supplied Home Depot stores with the stuff and it's changed its name to Old Castle and to YardRight over the past few years if I'm not mistaken... but it seems that it's primarily found only in Northeastern Home Depot stores. I'm having a really hard time finding it or a similar product anywhere in our area. The closest thing I've found is a product called "Sandtastik" on Sears' website but it's pricey compared to the stuff I'm actually trying to locate ($20 for 20 lbs. versus $4 for 50 lbs.). If any of you have seen any silica free sands, would you let me know? Thanks!

Nevermind. Found a great deal on sand through Marco Rocks if anyone else might want any.
