I found the sim and the people who run it to be very reasonable. They gave us a good intro to the cockpit layout, didn't rush us and it was a ready when you are kind of deal.
Take-off to landing; probably 20 mins to half an hour. Despite my misgivings re my efforts I still came away thinking that they had been very helpful to both me and the other guy. Wish all sim instructors were as un-stressed as these guys.
