Recently Lou posted a webpage of Aerosim where they sell B737 sims for US$ 500,000 (bargain!!). Actually, they can be much more expensive when equipped with a motion system and complete wide visual system.
This week I was in the USA to check out our motion system for a full flight simulator of the Hawker 800. This thing goes for approx. US$ 6,000,000!! On these sims you can earn your type rating without ever have flown the bird before.
Being only a real world GA pilot, I found the Hawker to fly smoother and easier as any Archer or Cessna does. But still, nothing beats the 737 :-)!
The photo below shows the Hawker 800 sim. We (the team I work with) did the motion system. The owner of the simulator owns an easy webpage: www.simulator.com, which is nice to look at.
