I’ll offer my two cent here, because moving to Magento is a costly decision. If you don’t have people on your team to handle issues with something like the slider, then I’m going to recommend you look at other solutions, like Adobe Business Catalyst or similar hosted e-commerce platforms. Really my friend, Magento is for people with time and coding skills, because you’ll need both to get Magento running the way you probably want. Shoot me an e-mail at kevin no-spam at woolf dot com and I’ll get your slider up, but seriously do a cost analysis among these e-commerce systems. Even with my skills, I’m still not exactly thrilled with Magento and might eventually move to a hosted platform myself.
