figured I would chime in here after reading some of the posts the reason for a sim is to get some stick time and practice, right?
I won't be bashing a company for trying to make money on a product that it has spent $ on R & D they are in buisness to make money , that is one reason why they dont sell add ons to the G-2 and some tech reasons as well.
all the sims mentioned are fine from what I have seen the G-3 is far better than the G-2 in graphics and flight performance and in the long run you want to recreate your flying as realistically as possible the graphics are way better on the G-3.
as far as cost Towerhobbies is selling the G-3 for 200$ then giving a 25 discount on 200$ orders and offering a 25$ gift cert on top well that looks like 150$ to me not too bad the price of the average ARF the AFPD looks like a nice sim also I just happen to have the G-3 and like it.
