It's a strange question, but does anyone know of a commercial version of osCommerce? The reason being is that timely, knowledgeable tech support is a must for the project I will be using with this software and the open source version only has user-to-user support, right? Of course, any commercial version I select would have to have good tech support.

I know little about PHP but this software comes installable with my new hosting service (one click of a button), and I've heard good things about it. This is an experiment I want to present to my boss (only if it works out) as proof that we need to progress to a PHP shopping cart.
