Hi Rob. I recommend purchasing Databridge and eCart, with these tools you can go beyond the Wizards that make up part of these extensions as you can go very much into advanced features if necessary. There are no limitiations of these extensions since they can have custom coding applied to them. The Wizards are good, but the extensions provide far more flexability in terms of the server behaviours. If you want help then I am perhaps anyone else on this forum would be happy to help.
