Pretty much indistinguishable from new, I got my 7D refurbished and I can really find no faults with it.
I also got my 7d from the Canon Loyalty Program (CLP) around the beginning of 2011 and it seemed brand new. I haven't checked the shutter count on Linux but the body seems to be in great shape and the screen still had its plastic cover on it and all of the dials/controls feel really tight.
