Is the nikon af p 70 300mm f 4 5 5 6e ed vr worth buying used?
I'd say yes, it's a sensible used buy. The site's view is that a body or lens a generation or two old often gives you most of the performance for much less money. This one is a stabilised autofocus zoom that covers 70-300mm on full frame, and its aperture of f/4.5-5.6 is fine for daylight and sports-style shooting, though it's not a low-light lens.
It fits a long list of Nikon F bodies. If you shoot full frame, the Nikon D750 is a solid partner. On a budget APS-C body, the Nikon D7500 or Nikon D5600 will work, but remember it frames like 105-450mm there.
Whatever you buy, budget for a new genuine battery. Read buying used before you commit.
