What do you use for a free e-commerce web app that can run smoothly on a typical shared host and fulfill the needs of your average small retail business?
Magento is powerful but has a nasty learning curve (one for templating and another one for coding) and doesn't run well on your average, cheap shared host. Documentation seems sparse (last I looked).
OpenCart looks like a good cart but it has code vulnerability problems and some developer temper tantrum issues.
osCommerce and Zencart both seem... crufty, I guess? The code seems kind of outdated, sprawling and somewhat hard to work with (at least, last time I looked it did).
So what do you use and why?
