Humidor size (carrying capacity), humidifying system and exterior decorations will make the difference with prices. The standard humidor will come with a dial type humidity gauge and a humidifying element (plastic box with a sponge inside). Keep this sponge wet with antifungal humidifying solution and keep the gauge at 65. It will stay there as long as you check the humidifying element regularly. I got a bargain humidor like, This one . That was 5 years ago and it still works great. You have to look around but you can get real bargains on humidors. A good shave in the morning and a good bourbon and cigar in the evenings make for a well rounded day.

PS: When you first get your humidor, wipe the inside down with DISTILLED water and allow to sit overnight. Then you can place your cigars inside and maintain your humidor. I check mines once every 2 weeks.
