What happened to OsCommerce, nobody use that anymore?
I'm currently looking at doing a bit of professional development with a eCommerce solution, I'm die-hard SilverStripe and especially Sapphire, but decided I'd look at what others are doing and maybe go back to being a php developer, instead of a SilverStripe developer.
I tried Magento yesterday, and although it was very feature rich, the install was buggy and it took 2 attempts to get it going because I was using a development server without a valid ip address. I then managed to add some products, but to get to them, I had to go to Site Map > Product Site Map, there was plenty of tutorials around to get them on the home page, but none of them worked. So it looks like it's a large learning curve, and you'll probably need an expert to manage your store.
I've just read this thread and am going to try the burnbright branch today, some good info here so a good thread to bump
