Generic humidors

Thinking about stepping up from my useful though somewhat undignified "tupperdor" to a real humidor. I refuse to spend hundreds, if not thousands, on the higher end humidors as aesthetics mean nothing to me. I just want something that will take good care of my sticks.

What's the story on the generic humis that just about every online cigar vendor carries? Without a name brand to go by, it seems hard to get an apples to apples comparison between websites much less have any idea of the quality of the product. Are these things worth looking into?
