It just depends on how you like to buy. When I ordered mine, I knew I would buy mostly boxes but planned on having singles as well.
I ended up with a NewAir with 4 shelves and 1 drawer. Right at 1 year later, I'm playing tetris with 30 boxes on 1 shelf. The few singles I have been gifted, are in a small desktop humidor.
I've found a 100 bottle EuroCave than I intend on purchasing that will give me much more space to expand... Can't let my girlfriend find out about that part though. I've convinced her that it will "look better" and will hide my cigar collection so she's on board.
