Actually the quality of the photo on EBay is probably as much of an issue as 
the screen calibration.  These images are seldom taken under controlled 
conditions and it is almost impossible to know if the color information that 
might be in the meta data of the image is correct and almost none of these 
images will have a profile embedded.  So even with a properly calibrated and 
profiled display we still don't know if the red we see on the screen is really 
the red of the actual object.   This is also true for most of the content on 
the web and we have only had color managed browsers for a fairly short time so 
it will likely be some time before the issue is even close to being largerly 
resolved.
