Can we get back to the OP's original question? (Oh, that was me.) As others have pointed out, I am, indeed, interested in the "value for money" question. And I am interested in your THINKING about this. Why some prigs equate your THINKING and REASONING with a meaningless question is something they should take up with their psychiatrists.
What is it about an M8.2 that would get you to buy it over the far cheaper used (but near-mint) M8? The reason this question has significance is that the two have, not nearly identical imaging systems, but TOTALLY identical imaging systems. So, the images they make are exactly the same. This is not at all true when other manufacturers introduce a new digital camera, which by the way, is usually CHEAPER than its predecessor, not more expensive as some self-styled experts here have claimed. So, when you buy a new high-end camera over a used previous version, you are getting a TOTALLY DIFFERENT imaging system from the predecessor's. For example, not only is Nikon's D300 cheaper than the predecessor D200 (sorry Roger), it has a TOTALLY DIFFERENT and vastly improved imaging system. That makes the value proposition pretty clear when buying a new D300 over used D200. This value proposition is not clear at all when it comes to the M8 and M8.2, since they have exactly the same imaging systems.
That's why I asked the question and that's why I am interested in your thinking about the matter.
