If you think you need 100 capacity then you should probably be getting at least 200. Try http://www.tampahumidor.com. They have a nice selection and good prices.
I would recommend going to http://www.cubancrafters.com
I purchased my first humidor from them and am completely satisfied with my decision. I got a great 150 ct humidor at an awesome price....only thing is, I've gotta get another one since I'm running outta space!
