NNF, my wife uses those style boxes to hold the beads from her beadwork. Great boxes.
Gutterboy, my wife bought hers at a craft store called Michael's. You'd be surprised at what you can find there.
I use a tote style rolling tool chest made by Craftsman. Picked it up at Sears really cheap. I use smaller Rubbermaid containers similar to what NNF posted inside the tool chest for holding smaller bits and pieces.
Mine holds three sets of wheels, two radios, a gallon of fuel and on two stacker style pull out trays everything I need in spare parts.
