I wouldn't recommend prozilla.com. While it is possible that they have changed, and please correct me if this is the case. The license system that they use for their scripts is terrible. On about 50% of the servers I've tried to install their scripts on, the license only validated "example.com". If you went to "www.example.com" it would display an invalid license error. I opened a ticket in their help desk and after about a week and a half i received a reply. They assured me that the problem was with the server and not with the license system, even though a good amount of others posted the same issue on their forum. They ignored all posts regarding this issue (I wasn't the only one), and they eventually just removed their forum because there were too many complaints being posted. I have, however, heard many good things about dotcombuilder, and I recommend that you take your business there.
