Ok, after reading this thread, I decided to give it another try and have fun with Daz´ surface tab.
Wonderful, is all I can say.
You can do so much bump and displacement, opacity and diffue maps. It´s fabulous.
I´m working on a pic right now and will post the result when I´m done.

So, honestly, you most likely wnt get the results you see in the promos with Daz, but you will get a whole variety of interesting possibilities.... if you know how to deal with the surface tab and got a hell lot of time
