The script is free this is version 1.0 and its easy to set up. THe admin Section of the Script is easy to access and easy to use. You add your domains and list for sale, offer, or not forsale and You can link your website to them. So people can buy the entire website.

The script has been out for a few months that I know of but gaining popularity from domainers.
