compare wood, aluminum, and fiberglass

Hi all:
I am the ultimate newbie and have been reading everything I can get my hands on. Can anybody point me to a thread or website that discusses the relative merits of covering the outside of your TD in wood, aluminum, or fiberglass?
I know that each material has it's good points and bad. I'd like to see a comparison of durability, cost, and ease of maintenance, as well as a description of how hard or easy it is to work with these materials.
I wasn't quite sure what search terms to use to get an answer to my question--although I'm sure this topic has been discussed previously. Any help would be much appreciated.
