If aesthetics aren't a priority, you could do what I did -
Took my old side-by-side refrigerator/freezer, and
filled the fridge side with 3lb.+ of beads.
And a bunch of boxes.
Fairly airtight, relatively insulated, it works great &
has lots of shelves for storage. And if I need to
expand space, I still have the freezer side.
Just don't plug it in.
You can pick up an old refrigerator in the classifieds
for very cheap. Clean it, wipe it down with distilled
water, line it with spanish cedar if you want, & voila!
Then with the thousands of $$ you saved by not buying
an Aristocrat or such, you can buy lots more cigars.
