I take it you mean Euro?
I've heard of 1D2's going for about that..
Personally, I use the 70-200 with a 1.4 rather than the 300, but 800 seems okay if it's that new. Also if it is sticky, send it to Canon for a service. I think it's 2 pro cameras and 3 L lenses to be a CPS member, so that might take you there if you're not already.
