I will be traveling continuously for 2 months and will be taking a bunch of pictures, but won't be bringing a laptop. Does anyone know of a way to copy photos from a memory card to an external without a computer? Is there some sort of (reasonably priced, around $150 ideally for about 100gb) way to do so? I saw these options (http://photodoto.com/portable-photo-storage-buyers-guide/) but it seems a little too expensive for the amount of memory. Does anyone have any suggestions other than buying additional SD cards?
