I am studying inventor 2008 right now but our course manual is not that so effective, and i wanted to buy a book as a guide to be easily understand the basic. Can you please give me some idea which book is better for a newbie like me. I search the internet and I found Autodesk Inventor 2008 essential plus and engineering design & graphic with autodesk inventor 2008. Some guys commented on the preivous one as an incomplete book without the tube and piping. So which is better on either of the two.

Thank you for your reply.
