Thom Hogan's site,
www.bythom.com has lots of reviews including this lens. Bjorn Rorslett is considered by many to be the authority on Nikon lenses,
www.naturfotograf.com . I use the ED version and it is a very good lens but most consider it slightly soft at 300mm and advise to zoom back a little for max sharpness. Mine is pretty good at 300mm if closed down to f8/f11.
