I have seen the 1DMkIII prices dropping with the release next month of the 1DMkIV. The 1DMkIII is running $2400-2200 down from $ 2700-2500. Further drop or has the market somewhat stabilized
I wouldn't buy a MkIII with someone elses money, "Unless" I could give it an absolute thorough workout which is rarely an option when buying over the net.
