I agree with @StogieNinja
. Be realistic about where you're at in your exploration of cigars. Looking ahead a little is okay (I liked @StogieNinja
quantifying it at +25%). But a huge tupperdor or coolerdor that's way too big is not a plus at this point. Aside from just being more space to try to maintain proper RH (more space means more media, which means more cost, perhaps significantly more cost), having that much excess room tends to encourage you to just buy, buy, buy to fill it up before you've really built a foundation of knowledge, gotten to know your own tastes, and yes, found out that those tastes can change significantly in your early days, weeks, months, and even years in the hobby.
I think @DSturg369
's comment about the 150 qt was meant tongue-in-cheek. But just to give you an idea of how much storage capacity that relates too I checked my spreadsheet to see how much is in my 150 qt that I use exclusively for box storage. It's still got room for several more boxes and many of those in it now are only partially full. And there's still 1,250 cigars in it! I'd say about 1,500 is max'd out. So extrapolate from that that the 74 qt tupper that was suggested will hold about 750 cigars. That ought to scare the crap out of anyone new to this. If it doesn't, get your calculator out and multiply that times the average cost of the cigars you're buying!
Take it slow. Plan for the immediate future and learn all you can. The far flung future will take care of itself.
