I've got a 1DsIII in mint condition with about 8k clicks. It performs flawlessly, and produces excellent images. No functional or cosmetic issues. I have an L-Bracket and a couple of spare batteries that I'll offer to the buyer at a very reasonable price.
It's more camera than I really need. I'm planning to move to a combination of the 50D and the new 5D replacement sometime this fall.
I'll sell my 1DsIII for $6,250 net to me, or trade for another body plus cash. In terms of trades, I'd consider any of the following bodies: 30D, 40D, 1DII, 1DIII. I'd also consider lenses in trade: 500/4, 200/2, Zeiss 21.
I can take some photos of the camera on Sunday. In the meantime, contact me with any questions or interest.
I have a long history of positive feedback on this forum. Just do a search on my name.
