[Zope] Shopping Cart

Hi; I need a shopping cart for an app I'm building in Zope. I've worked with a cart built in PHP and been quite happy with it. I notice that the only product currently available for this app in Zope is zCommerce. There has only been one developmental release of it and that was well over a year ago. Has anyone had any good experience with this app? Or, would I be better off trying to port the PHP app into Zope? Or proxy-passing back and forth between Zope and Apache? TIA, BenO
