The rolling tool chest is nice if you have the room for em.

But for stacking in closets I am putting my cameras in zip loc bags with silica packets, then putting em in portable hand tool boxes like these...

I get em at Sears, K-Mart n Home Depot for around $15 or so when I see em on sale. Take the top shelf out n they can hold a complete MF kit. Label the outside, it makes finding my stuff that much easier.
