I'm looking for an easy to skin and customize e-commerce package.
I've been reading good reviews about Magento, but it seems to have problems with performance. I've tried osCommerce before and found it to be pretty painful to modify, but I hear zenCart is better... but the latest release of zenCart is nearly a year old, so not sure how up to date it is at this point.
I tried hosted e-commerce with Shopify, and while very easy to use and template, its customization options are a bit limited (the templating language doesn't even support basic logic operations, which makes it pretty inflexible).
I'm almost ready to try writing my own in rails using ActiveMerchant, but while that will give me ultimate in customization, it's going to take much longer when I have to reinvent the wheel.
I'd be happy with a php, ruby or python based system, I know enough of those languages to be able to customize the system if I need to as long as it's well-organized and documented code.
Anybody have experience with something they'd recommend, or conversely, recommend staying away from?
