Beginner Questions (Ask Them Here!)

Ok, quick question from a newbie.

I am buying my first humidor and have my eye on The Pompeii (http://www.cheaphumidors.com/HUM-100PR.html). I think I would like one with a glass top but have seen scattered comments about glass tops potentially causing problems. Could any experts please advise if this is generally true from experience?

Of course, would also love to hear the thoughts of any one that owns this particular humidor.

Thanks very much
