In my opinion, to pay $1400 for a 5D Mark II with 43,000 actuations is a bit high. You can get one now brand new with zero actuations for $1799, and my guess is that the price drop and the move to clear out inventories of the 5D Mark II will markedly affect the Ebay price soon, and quite possibly make used 5D Mark II's with just a few thousand actuations available for the price you are considering. Even though the camera is built to live considerably longer than it has thus far, forty three thousand actuations is quite a bit more than a mere test drive. I think that seller is going to soon have trouble moving the camera because there'll be so many others available at nearly the same price but a fraction of the actuations.
