My wooden humidor isn't holding up to the winter temps.Looks like I'm going to have to pick up a cooler this weekend. Any suggestions on good brands/sizes? I don't have to relocate very many sticks, just have 40 or so in there now, so something small with a good seal should work fine. Also, I do not shop at Walmart (I refuse to enter that place). So keep that in mind. I don't know if they are all basically the same or not, just wondering what you guys use. Thanks
