I know that some people Bad mouth Harbor Freight, But almost 2 yrs ago I bought there really large roll away bottom and top, It the U.S General Brand, Red in color, and I have to say for what I paid for the top and bottom it was a steal. Best tool boxes I have ever bought. Roller bearing drawers. Has that nice and heavy feel, not a flimsy like feeling. I'm no professional so I don't use it 9hrs everyday 6 days a week but its one tough S.O.B. I think I paid $400-$450 for both. I quickly got rid of my craftsman boxes, they couldn't stand up to that cheap Chinese stuff. Just my opinion.
