My company is in the process of changing over from Autocad to Revit and I am one of the guinea pigs. So far it has been pretty challenging but I'm slowly getting the hang of it. It is pretty sweet what things end up looking like. At the end of all this I doubt Revit can do a project cheaper than Autocad though. It seems too much information has to go into Revit.
Here is a screen shot from my current project. Its an expansion of a Walmart Supercenter.
