Also beware of some 80-200 f/2.8. There are some designs that are push-pull based, meaning you do not turn a ring on the lens to zoom, but push the lens out and pull it back. I've heard that push-pull can be rather inconvenient when shooting upwards or downwards as the lens extends or retracts due to gravity. When the forces that hold the barrel in place are not strong enough carrying such a lens around is probably not very funny.

There were three generations of AF 80-200 f/2.8:
80-200 f/2.8 (made in late 80x / early 90x), with push-pull zoom and one ring.
80-200 f/2.8 D (made since the late 90x), with conventional zoom and two rings. I think it's still being manufactured?
80-200 f/2.8 AF-S (made in 2000-2004 I think), replaced with 70-200 shortly after that.
Both 1st gen and 2nd gen lenses are screw driven and have very similar build quality (all metal) and optics (sharp even wide open and smooth bokeh). The main difference is that 1st generation (non D) has *very* slow AF gearing and not really suitable for action shots. The 2nd gen lens has probably 2-3 times faster gearing, closer to the newer AF-S 80-200.
As the 1st gen is just too slow, and the 3rd gen is very hard to find, I guess you would be aiming for the 2nd gen lens which still can be found new, for some 700 eur.
Regarding the zoom creep in push-pull 80-200: I've used it to shoot in an air show, and no, I had no problems shooting upwards. I think mostly Sigma / Tamron zoom lenses are plagued by the zoom creep issue :-)
