I was also considering using the fridge for both wines and cigars.
I am going to just use it for cigars, though.
I told my wife I would buy her another fridge for the wine. Maybe a dual temp unit.
I am having Chuck make me some drawers (2 doubles and 3 singles.) I thought about doing it myself, but I want them to look nice

I also smoke maybe 1-2 a week and buy/try from my local B&M.
Haven't bought a box yet, so it is going to look pretty empty when my shelves come in. I'm in no rush, though. Still trying to figure out what I like best.
