When you look at racks online make sure to look and see if the tubs are included. It seems like tubs are not always included.

I love building so I am a DIY person. Lowes or home depot will cut the wood to the size you need, I think they only charge $.50 a cut or something. Most people use MCP (Melamine is just the coating, not the wood itself). I like using the 40qt sterilite tubs from walmart, to me they work the best. http://www.walmart.com/catalog/produ...ct_id=10401057 Also its usually cheaper buying those online and then picking up at the store.
