Heather User I have been testing it out for use in inventorying an estate with lots of books and music CDs. So far it appears to have the most comprehensive data pulling of information (e.g. multiple seller sites, used and new information). That is going to help greatly in valuing the estate. Right now it also comes with a free scanner if you get the bundle in CD form. Other software packages that do similar are more expensive and/or do not have the ability to attach to a separate USB scanner. If they do, it is proprietary to their software and can't be used with any other software.
