I'd say go for using G2. What ever bad habits you might pick up won't be ingrained because you'll only have a limited number of hours on the sim before you get out with your instructor.

In the club that I belong to, recently we've had newbies qualify for solo rating, not needing to fly with an instuctor on a buddy box, within a matter of weeks because of the stick time that they've had on simulators.

Good luck.
