On a Ego or Geo 45,000 would be nothing.
don't know about the other as haven't used them.
I would look at how the gun has been treated, barrel rub and the odd mark is to be expected, the padded case, box it original came in, tools etc suggests it has been stored correctly and probably looked after ....
lots of marks or damage, no box, no tools, different coloured parts, not with keeping with how it was from new could suggest it has been a team gun and not loved
