I've just upgraded fro acad architecture to the design suite. I will still have ACA/acad but now also have revit and 3D max design. It was an offer I couldn't refuse as it was such a low price for so much software. My subs increase, but now I can transition to revit at my own pace. Revit has its drawbacks but the construction industry is moving that way so I have to follow.
