I just wrapped up an ecommerce site using ubercart, and started looking into magento, which brought me here. I do like Drupal as a CMS, but had some issues with getting Ubercart get setup. Things like marketing, coupons, and customer messages (thanks for your purchase) were not so easy to customize and setup.

That said - I did have a bit of trouble getting magento setup, but I got through it, finally.

In any case - has anyone heard of this:
