Does anybody have any recommendations for good and relatively inexpensive storage containers? I saw some at Target by OXO brand that look really nice and have an air tight seal at the tough of a button (http://www.google.com/images?q=oxo container&oe=utf-8&rls=org....)

I'm hoping to find something cheaper since I'll be getting 15-20 of them.

Thanks for the suggestions!
