Really love Lemonstand (http://www.lemonstandapp.com http://www.lemonstandapp.com). Super well developed and has been easy to customize. Great support. For simple, quick projects, I've used Shopify (hosted) and had a very good experience with it. Their team is very active and constantly adds new features and improvements. Our experience with Magento was a mess - we found it very difficult to work with, and far overkill for what we needed. I've heard good things about Spree (http://www.spreecommerce.com http://www.spreecommerce.com), but haven't used it myself yet.
