What should I be looking for?

I'm going to be looking at some new humidors and the last one I had was really junk. This time around I want quality without breaking my bank. I'm looking for a humidor the size that can hold around 25-50 cigars. When I'm looking at these humidors what are some questions I should be asking? And what should I be looking for while I'm inspecting it that will show me it's a good humidor?
