We just bought some aromatic cedar for a closet at Home Depot and I'm sure the other big chains have it also. The T&G boards were somewhere around 1/8 or 1/4" thick and 4 or 5" wide. You either have to glue or face nail them down since they are so thin and the tongue is so small that you will not be able to nail through the tongue like you do with flooring. If I recall correctly, one package did 16 sq. ft. and was around $18. Don't have the packages here or I could be more exact.
