I picked up one of these, and really like it!

I can fit 2 decks in it, one in each tray, then where the "oversized" cards are supposed to go, I put two top loaders which hold each commander. I keep the rest of my decks in fat pack boxes... but I am looking to either get more of the tower boxes, or find another solution for bulk decks.

I keep my dice in a Canon lens bag like this They make great dice bags, and dont cost anything if you buy a fancy lens first!

I usually carry everything in my camera backpack it works great to have a backpack that is already designed to hold heavy junk. (plus, I can bring my camera too)
