There are many, many, many options out there, but I still couldn't settle with one. So I'm asking for a little help here, and hopefully this will also work as reference to someone else.
Ones that looks nice to me so far include wordpress getshopped, opencart and magento. But they all need to install and configure and try out for many different features, which I still don't even know if I'm going to need or not. That is the "solution" part of my question, since I'll also need a host able to handle it and, preferably, supporting the platform updates.
Features I do need are a ticket system (which opencart sure doesn't have built in), so I can customize a custom made product for instance, and customizable user interface, as easy and as much as possible. In here I like to take squarespace as an example. Really easy to customize. In fact, it would be great if the shopping cart would offer similar drag n' drop features.
I don't care if it's .net, php, gae or python. Actually, that's about my reversed order of preference language-wise, python being preferred. I care a lot more if it's easy to support, modify and migrate if needed (of host, platform, database, whatever). Also I do want a way to try it out hassle free. Open source is always better but not necessarily best.
I hope this is not "too localized". And please, feel free to suggest better tags. Bottom line:
