Ya the Boveda packs kick ass... On the C-vault just do a google search for Stainless steel airtight bowls or canisters search around I found the exact same thing as the c-vault ( except no handy hanger for the boveda pack) on ebay for whole set of 9 for 30 bucks.
I just did a quick search and found these (
http://www.naturalathome.com/product/airtight-watertight-stainless-steel-food-storage-containers ) so dig around you could find em ALOT cheaper. I have found alot of products are just re purposed and re-branded for MJ and the price goes up 3-5 fold.
Examples.
1. 420 scope ( hand held microscope you can by online for 3 bucks or go to Radio shack and by one for 10 bucks
2. C-vault (see above)
3.
Bubble machine 350 -400 (small machine to extract hash) these are just portable RV clothes washing machines I found on Amazon for 50 bucks
