I had one from 2004 (I think) and actually tossed it at some point. It offers some information about manufacturers, brands, and the blends that go into the cigars but I very rarely used it. I'd say if you can get it cheap or want to know that detail get one and keep it near the computer or while smoking so you can leaf through it. Might help if you're starting a cigar diary or keeping a log for reveiws.
