Too small IMHO. You are better off getting a 48qt cooler from WalMart. By the time you add 3-4 drawers at $30/ea, you are well over $200 and you still need beads. If you are worried about temps just freeze everything for 3-4 days then put them in the cooler.
Most domestic distributors already freeze their cigars at the factory or after they enter the country.
