I can't stand big plastic storage bins that grow in heft until they can't easily be lifted. Even worse is when they get stacked up so you need to move four awkwardly heavy bins in order to get at the contents of the fifth.
Sterilite makes a shelf-and-bin system that solves this issue... 25-quart and 50-quart bins. I like that they stack tightly, efficiently using all available space.
