I need a damn tool box

Where is the best/cheapest place to go to get a nice tool box (roll away and chest)? I have been eyeballing the Craftsman ball bearing griplock stuff. It seems decently priced, and the quality seems there. Matco has some nice boxes as well, give me some advice as to where I can go to save some money, as Sears will price match to anyone, as long as it is not a used product.
