Not sure about time or price comparison, but downwind.com.au are running a flight sim experience in conjunction with the Ansett flight sim center, they only have the 737 classic, but may be better than nothing and a whole lot cheaper (I think)?
Ultimate Simulator Event is Back!
Might be worth a consideration if it fits in your time frame and the classic will do as opposed to an NG sim.
p.s. I am in no way affiliated with downwind.com.au
