Zend cart = blah!
If we're not making any money yet, why throw down money up front for store software?
Your thoughts are appreciated.
Another option is Interspire Shopping Cart (http://bit.ly/9z96cl) - which is not open source but give you full access to php code base, design flexibility, a steady stream of updates, support, and new features.
Interspire also makes BigCommerce (http://bit.ly/bxyds4) which is a hosted shopping cart with solid front end flexibility.
I have used magento as well and there is just no comparison.

was a one night project long before I considered myself an expert in Drupal. Same project would only take a couple hours max now.
