Personally, I'd go for a wood door. I would just want to keep my cigars where it's 65-70/70, and dark. And, a wooden door I'm thinking would be lined with cedar too, giving you that much more surface to interact with the cigar environment. my 2 cents. Whatever you get, I'm sure you'll enjoy - gave me a laugh when you suggested your wife is tired of having a cooler in the dining room , so, I'll bet she'll enjoy it too.
