There is a device for this purpose. I cannot remember the name but I saw it on sale in Spain, I mimagine it should be in one of the large computer stores in Ireland or maybe online (). It is a device the size of a cigarette packet, had 2 AA batteries installed and could connect to 2 USB devices and transfer between them, without being connected to a PC. It was on sale for around 20euro, definetly a cheaper option if your camera uses the more expensive storage cards like the Memory Stick. A 1GB USB stick is usually cheaper than the other memory cards.
