Guys when it comes to flooded basements and models....
Rubbermade is your friend!
Trust me on this, even though most of my collection is in a storage area instead of a basement (or built and on display ), those have already paid for them selves to boot!!!!!!!!
Just look at places like Wal-Mart, K-Mart, Meijer, and the like for sales on that type of product. Not only is it easier to keep things dry, , but they stack neatly and they work great if you are moving and need to transport things!
