Random thoughts on storing Combat Commander

Now that I have Combat Commander: Mediterranean, I've been considering the options for storage. Each of the Europe (base) game and Med fit in their own boxes using the Plano containers (pictured) I have now. Three of these (20 spaces each) and the card decks fit into the boxes with the lids either flush or just barely lifted. The problem is - CC:Med is not really a separate game - it is an expansion (and in some ways "completes" the base game). I could of course just use GMT counter trays, but six or seven of these will fill a box and require the cards and maps in another box. The other issue I have with the counter trays is that I'm not sure the lids won't just pop off and dump chits everywhere. I'd also really like to have all of the materials in one container. A lot of the published scenarios and tourney scenarios require both Europe and Med. Then of course there are the expansions :

• Combat Commander: Battle Pack #1 - Paratroopers
• Combat Commander: Battle Pack #2 - Stalingrad
• Combat Commander: Battle Pack #3 - Normandy
• Combat Commander: Resistance!

These will add to the bulk of maps as well as add counters. At this point it almost looks like I need a tackle bag solution like I use for Command and Colors: Ancients. The problem with this is that the Plano boxes are too big for the little chits. While there are lots of chits, they aren't so plentiful that I need the kind of space that the C&C:Ancients blocks require.
This morning, I was over at Walmart looking at their tackle selection trying to figure out if I wanted to just use a tackle box and what might work. Then I wandered over to their craft section and there I found bead boxes. These smaller boxes are fairly flat and have 24 containers inside them (thus I'd need 5 to meet the current storage need and maybe a 6th for expansions. These aren't too bad for size (I'd still need some other solution for toting everything around, but the clear plastic should work pretty decently). The small containers have screw tops to keep the chits in. I'm kind of leaning this way if I can figure out a solution for keeping these and the cards and all of the maps and booklets together.
