If you need to use plywood, get a sealer for it so it can't get wet. Birch plywood is the cheapest and should be easy to find.

That being said, I don't think you will have a problem finding melamine. If you can't find it in the lumbar section, check the shelving system section.
I have a couple of my first racks that I ever built using MDF, a person would have to soak that stuff in water for along time before it would fall apart.

Would definately recommend melamine over it but MDF can be used for several years without any problems.
