Trust me when I say this because I was in your shoes not so long ago, if your going to buy a humidor, bigger will be better. I thought the same as you, "Oh, I only need one big enough to hold a few smokes as I don't smoke that often." Lucky for me I picked up a 50 ct box because in less than two months that sucker is full. If you are going to start with a tuperdor than no worries as it will be inexpensive to expand as your collection grows, but do make sure you invest in some sort of humidification device like CC suggested.
