I loved this camera.  I've been a Canon guy for a long time and have been thinking about moving over to the R series and this did it for me.  Honestly, I hope you can get it working and use it for a long time.  It is great if you can.  It's a Canon EOS 1DX.  It's got two CF slots and I've tried both with new and old cards and it says "Card (X) cannot be accessed, reinsert/change the card or format card with camera."  I've put new batteries, everything and nothing.  I did do the research and yes, the cards can be read on a card reader so it's not the card.  Some say it's the battery door, some say the card door...well, like I said, I have been wanting to go the R series so here's my reason.  It comes with one battery - a legit Canon LP-E4.  Body cover, strap and if I can find anything else that came with it - it'll be a bonus.  Happy bidding.
