You will need a humidifier sooner later, the cigar box will not sustain the humidity. So dont worry about it, your "investment" will be justified. That is if you dont upgrade to another system or much much bigger sized tupperdor. I told you what ever sized your thinking initially double it. Hahahaha. Anyways, i glad you gotta the bug. For more info on cigars besides cigar-reviews.org, the link below is has great wealth of info, and they are really nice bunch of guys. Look at their video reviews, just hilarious. Their video reviews are spot on to my taste bud.
They are internet sellers, slightly more expensive than COH but they inspect each and every box and grade it to 3 categories. Which is good so that, you know what your buying, even their economy class is a touch better than your duty free shops. But be warned, for wallet draining experience as bad or even worse in my case than Kerbau.
