The main difference I can see is one of style. Some humidors are made out of nice materials that make it an attractive piece of furniture. If you aren't necessarily concerned with how it looks, then an inexpensive humidor works fine. And if you want to build your own, there are many guides on the net to how to build your own "coolidor".
