If you can wait a little longer, I'd recommend you wait for the next release tentattively scheduled for March or April, 2007. There is currently very limited content in version 2.0 so you will end up spending a lot of time creating custom content.
Additionally, since the product is so new, there are limited support resources available at Autodesk, as well as the dealer network.
My firm is presently in the middle of implementing this product for the first time on an active project and it's been tough so far. The product works but I think it needs a little more seasoning before it's a completely viable product for consultants to use.
Hope this helps!
