Does anyone here use Reaktor 5?

[Future Proof]

My copy will be arriving today. It was too hard to resist, the sound quality is just incredible, and totally smokes Reason, especially the bass. Only problem is, I don't have a PhD from MIT and there are no tutorial books/DVD's out there and most software manuals are not written all that well.

How badly will I be suffering on the learning curve? And does anyone have a Reaktor 5 file that they could send to me so I can pull it apart and analyze it?
