Once again, I am out of space; my initial upgrade was to a 1200 capacity, it is now full. I am looking at an Aristocrat M+ THC. Need some advice as to whether or not the Temp Control is worth the extra cost. For many years my humidors have been in a 68 - 74 degree enviornment, with no problems (guess I answered my own question). For any of you with Temp Control, would appreciate your thoughts/recommendations. Thanks
