Check out Sears “Craftsman Club”. They have some greatly reduced prices on their “Premimum Storage” boxes, I think around 40% off.
They also have a vo-tech student one time offer of 50% off on a tool set and toolchest. Link Below:

Earlier this year I bought the 52″ 12-drawer cabinet and top chest. They seem to be decent quality so far.
The lower cabinet drawers are a 22-1/4″ wide by 16-1/4″ deep.
The top chest drawers are 22-1/4″ wide by 14-1/2″ deep.
I used my 50% discount to get the 540 piece tool set also, and found a place “Foam Fit Tools” that makes pre-cut foam inserts for the tools, although they are pricey.
