what about a usb flash drive via the duo memory port? Couldnt they make some converstions and get a usb flash drive to work as a dou stick? (1GB Flash drive is like $50, compared to around $120 for a duo)
i suggested that usb disk drive a while ago because like you said they're a lot cheaper

It can be done and has been done. You just need an external usb hdd that has host functionality such as the Steno. Not just any USB HDD will work.
