Gould Genealogy in South Australia sell them and accessories.
I did a class today, by Carole Riley at SAG and she showed us how to get the best out of the scanner and how to stitch large documents or photos together, once they are scanned. Software comes with the scanner. It runs on 4 AA batteries and you can use rechargeable ones. It comes with a 2GB SD card, it has the stitching program on it. The cove comes off and you flip it over for scanning larger items.
