You can get various levels of quality in luggage, some more sturdy than others. Other sources are small folding hund truck types that are designed to haul luggage as well. Then there are small "filing cabinet" types that are for salesman to carry catalogs and papers. The last two are available at office supply stores. Also look at hardware stores and sears in the tool section, there are vasious wheeled toolboxes like that as well. I'm going to pick up one of those tool boxes for all my cordless stuff soon.
