I bought a 12 pack of hygrometers on Amazon.They work and can be put inside any Tupperware containers. 72 is good if you live in very dry regions, 65 is better if you live in very humid regions. I thought about the same thing of having a large humidor made from a cedar chest. The problem is being able to find what you want when you want to smoke it I think they'd be great if you were planning on storing stuff for a long time but a simple Tupperware container that you can open and search for the one you want to find, some thing that's worked out really well for me even though I have like 14 of them.
As far as cigars go, I have learned here Gurkha is a brand left alone. Smoke what you have to see what they are about, but if you get on cigar bid, you will notice they sell for way less than other brands. They have become infamous for being a lot of flash and fancy labels more than having much flavor. That is my personal experience.
look on YouTube at cigar reviews. I usually watch Cigar Obsession, and I've learned a lot. It's like everything else, cigar smoking is something that there is a lot to learn about. The less we know about something tends to make us think we know a lot about it, generally that's how it works and the more you look into it the more you find out there's tons of information and things to know about smoking cigars and pipes. I just bought my first Savanelli 320 oceana , and started smoking pipes again. I'm still preferring cigars more. Just more satisfying for me I guess.
