I got a brand new 80-200mm AF-D off ebay about three weeks ago and it's deffo now my fave lens. Mine's the twist zoom and not the push-pull zoom.
AF is fast and very accurate, and IQ is beyond belief. Handling is great (it's as solid as a rock build-wise) and the textured finish gives good grip.
I use mine mainly for slower moving and static objects so can't really coment on its use for sports but that said, from everything i've read (and what other users on here have said) it's pretty good, although not on par with the 80-200mm AF-S, which is faster.
Any bad points? Well, not really. Colour fringing can happen when you're shooting into really harsh light with a really, really (and I mean black cat against a white sky) high contrast scene, but that's something I have happen to me once in a blue moon.
Here it is at 145mm / f5.6 / 1/320th sec / ISO160
Here it is at 200mm / f7.1 / 1/200th sec / ISO200
For £600(ish) it's a bargain lens
