The EOS-1D C was won on eBay for only £4100 buy a friend of mine, guy selling it was from a massive firm and clearly didn't care for the value and he just got lucky that no-one saw it and bidder, its 3 months old with only 1000 shutter count.
I put it with my 70-200 and 600exrt as I mainly do weddings, and these 2 are well used at those.
I have a 1D-X & two 5D3's which I use, he was going to do the same although won the C for less money!
