Where to buy good semi-cheap ratchet socket set in USA?

Two cheap alternatives are to use a Tupperware container or Sears sell small canvas tool bags for about $10. That's a lot cheaper than buying a new set up tools just for the case.

When Sears has tool set on sale, I've bought them because that's the cheapest way to buy replacement parts sometimes - then I throw the plastic case away because it takes up too much room.
