without X-ray vision, you can never be really sure of any s/h hand item unless there is visible damage, and even then, it could be repaired so as to hide it - I am not just referring to carbon bars.
I have bought a couple of bikes with s/h carbon bars and a couple of s/h bars and all is good - there may be some cosmetic marks due to the clamp but if that is all, then probably you'll be fine.
re: easton carbon bars - how about these chinese carbon riser bars: £ 14.39
light and strong without any branding logos (I have a set and not broken yet).
