I'm going to have a custom humidor made

[pub spears]

try looking up some info on Luan wood. i've read that it has some of the same characteristics as cedar, but is cheaper.

just a suggestion.

I think that you are talking about 1/4 sheet goods with a veneer of whatever on one side. Think 1/4 inch plywood or mdf with a finished side of oak, birch, vinyl, etc. veneer. Oh Yeah, maybe consider a glass panel door so you can oogle without opening if it's not going to also serve as a furniture piece.
