Your Local Thrift Store! Don't overlook this place as a possibility of finding a cheap high quality carrying bag. Yesterday, I was looking thru a large Bin in our neighborhood thrift store where all the used backpacks, cargo bags ect are displayed and at the bottom, I found a large, super high quality black Canvas Bag more then suitable for my Dahon Folder. The Quality is, IMO, equal to or higher then the Factory Dahon Bag. It has a padded Shoulder carrying strap as well as two Nylon, heavy duty Carrying handles. Its shaped like a large deep black duffle bag only it has a full length Zipper down the middle. I may have to make a little modification(or two) but at the Price of only $9.95, no problem. It has the Logo from some High School Athletic Team so I believe it was used for Sporting gear storage/ transportation in its prior life. Athletic Teams usually always have super heavy duty gear bags. I am thinking School Athletic Departments would be a good place to check and see if they have old ones they want to sell or give away. Costs nothing to ask,,,
