That's very true!

To produce an FX sensor costs roughly 9x (nine times) as much as a DX sensor - yes, 9x!

So if a DX sensor costs 40 USD, then the equivalent FX sensor costs roughly 360 USD. Now take a typical 3.5x markup for the end user buying price... ==:-((

Or look at it another way: Take the price difference of a Nikon D700 and a Nikon D300 and you get the idea how much more expensive an FX camera is.
