Listed on a daily deal, here's an Aluminum Hard Case with 'Pluck Foam' for customizing the fit of your equipment. I wouldn't trust them to handle my Lenses or DSLR video cameras, but for every other accessory they work great to keep things where they need to be and i'm able to store them on shelves or rack space.
I purchased a half dozen of these cheap cases a while back mainly to organize my lav mics, batteries, chargers, portable audio recorders, headphones, cables/wires, etc. Having a case also ensures you leave with what you came to the shoot with. Normally priced closer to $20 dollars, today's deal lands these Aluminum custom fit foam padded cases at just $9.99 + FREE SHIPPING (click here).
