I am looking for a free open source classifieds script using PHP. I have came across some and like to have some more inputs. So I can compare and decide what should actucally use. I am also experienced in Joomla. So suggestions about Joomla extensions are welcome.
Have you tried osclass? It's open source and it's just for classifieds.
You can also try http://open-classifieds.com/ . its also free open source classifieds script using PHP
classipress from wordpress is quite good and popular .. maybe you can take a look
You should try PHP Classifieds! they have awesome support and great themes. Those are not free, but god they worth it!
