$40 is hardly steep for a product that fully simulates an aircraft in almost its entirety. Not even the FMS is X-Plane technology, but custom plug-in, as well as the autopilot system and all displays. The aircraft cannot be started just by jumping in the cockpit and going, but by reading the manual and checklists and doing it just like the real thing. It is, in itself, a simulator within a sim! PMDG makes products that are $79+. Go figure there, right? Somehow, they are still about the most popular around for MSFS. I do believe that costs need to be justified, and I DO believe there is a threshold for costs of products ($79 is certainly pushing it quite a bit), but when you consider the man hours invested to do this stuff, it's insignificant. You'll get hours of enjoyment at your own disposal for the cost of a nice dinner at Olive Garden for two. Of course, if you can't manage that cost at this time it's understandable given the state of economies, but maybe it'll be something to gift yourself or save up for down the line should you want it that bad and are serious enough about how much you want to simulate in your X-Plane flights. The choice is yours...that's the beauty of it all!
