What do you think is the best ecommerce / CMS script to use? I have used oscommerce and CRELoaded for several projects, but have a new site to do and was considering using a different one. I like CRELoaded, and have had good luck with using it for SEO reasons.

I heard about one called drupal http://drupal.org/

I know there are others like Zen cart, but any way it goes, what are you guys using, and why do you like it?

If there are any advantages with one script or another for SEO reasons, I would love to know. Thanks to everyone for your time in posting replies, I greatly appreciate it.

There is no best girl for everyone, as you know :-) The same for ecommerce/CMS scripts

So, what is the best ecommerce solution for you depends on your requirements. For me, the best shopping cart now is Avactis (http://www.avactis.com). Earlier I used osCommerce when it was the best. Just check Avactis, may be it's the best for you.
