Buying used snap-on box Vrs new bigger china box

I've used a lot of work bay size boxes and I prefer a smaller tool chest with a bare top for a work bench.

I also like having the drawers split up between two sides, so I'm not sliding something open that is the entire width of the box, to get one tool.

The toolbox that I have is a 15 year old ball bearing Craftsman.

I like the idea of the blow molded cases getting kicked from the box into a cabinet for loose tool sets. All of my hand tools are organized good, but there are some places in my box that are accumulating junk that need to go away, before I decide to go any larger.

I've thought about buying a cart, but I don't like the idea of having my tools out in the open, with all of the dust that comes with doing body work.
