If you insist on no instructor, get Real Flight, and get VERY good at it. I mean REAL good at it. Then when you go to the field and take off, you will realize that the SIM doesn't feel like the real thing [X(]

You will have all the basic skills, but executing them on a live bird is quite different. You will freeze, go left when you wanted right, and there is no red RESET button on the controller.

My point, get an instructor.

PS, not putting down the sims, just don't believe they are the same as an instructor.
