A Basic Humidor Buying Guide

Thank you all for your knowledge and help.
I'm thinking to switch that humidor and buy a new one (see details of the new humidor in: http://www.thompsoncigar.com/product...38/pc/8389.uts). Anyone has used this humidor or knows anything about it. Please advise if you know. Thanks
PS. the humidor Im returning / changing is this (http://www.thompsoncigar.com/product...92/pc/8389.uts)
