Please suggest Joomla or Drupal software product theme?

I'm looking for a Joomla 开发者_如何学JAVAor Drupal software product site theme(preferably Drupal and free)? I have no problem if the theme needs some css hacking. Any suggestions?

Thanks

If you're selling the utility program and you're using Drupal, you should use Ubercart. (check out http://ubercart.org and http://drupal.org/project/ubercart ).

A good theme optimized for selling products is http://drupal.org/project/acquia_prosper

To get up and running with acquia prosper and ubercart in general quickly I would recommend the following project http://drupal.org/project/uberdrupal
