The cause of much of my grief and certainly the origin of my particular LLD is a wonderful independent, but non-objective web site reviewing nikon lenses. It is run by a professional (very) photographer called Bjorn Rorslett who has actual handson experience of all the lenses he discusses and rates them according to their performance on specific Nikon bodies.
http://www.naturfotograf.com/lens_surv.html#rating. He rates the 28/2.8 not very highly. He does recommend the 28/2.0, which I have, and is very sharp and a lovely FL on the D70. The other , more popular, better rated lens is the 24/2.8 in all of its various incarnations.
Another, much more opinionated site is run by Ken Rockwell, which is still worth a visit as long as you cross refer his views with other sources. He calls the shots as he sees them, and on lenses he seems very reliable.
