Agreed. I prefer to keep the ISO on my 7D to 800 or less if possible. I don't use high ISO NR, I shoot RAW, and I find that DxO does a better job than DPP at NR - ISO 3200 is usable in many shots.
I do wish the 7D had a user-selectable limit on Auto ISO - newer cameras do (including Rebel/xxxD bodies, and even my S95 and S100). Canon could add that feature via firmware, but that's not how they do things, so I have no expectation that it will ever be available on the 7D (but it will on a 7DII).
