Good planning, you usually want to go larger that what you currently have. The Humidipacks are great, but as your collection grows, you will need something that can better disperse humidity throughout your humidor. I like Xikar/Madelaine crystal humidifiers - being in Rhode Island, you would be able to go with a 100ct. humidifier for a 100ct. humidor, whereas here in Arizona, I have to get a 200ct. humidifier for a 100-150ct. humidor. Furthermore, you need to keep a steady eye on the humidity, and you can get by with a lot of hygrometers, but I like Credo's units best, personally, they have always worked best for be in displaying proper RH. I'm sure you are already well versed in this stuff, but I'm just adding my $.02!
