I bought one from a software developer on eBay (eBay ID=DVSTATE). The software he wrote was useless to me as I could never get it to run and he didn't reply to email after the first one or two. I was able to find generic software online that allowed me to read codes and clear them so it was not a total loss but don't expect the features to be over and above that unless you are lucky enough to have the software work for you.
