We are looking for a total comparison website or only a comparison script.

The script will have no external product feeds or any search grabber.
All products/data should be added by the website admin and/or product subscribers/publishers.

Most important thing is that the script can be altered for any product and can be used for any topic website, like for example rental prices website or maybe a hosting plan website

I prefer already made scripts (please demo Pm)

Regards
