Today I've found a link to a great comparison article (Newsforge) about mambo-phpShop and Drupal's E-Commerce plugin. The author does a really good in-depth review of both systems and finally gives an overview about the avantages and disadvantages of both systems.
It's really interesting to read about mambo-phpShop...if you're new to this and want to check if mambo-phpShop is right for you: check this article out.
