I agree, so long as you're OK maual-focusing, then the 1.8 is still a spectacular deal. You'll only really be using it for still objects, anyway, so you should be fine. Go for it!
I have to disagree on the still objects thout.
It's equal to a 75MM f1.8 on a film camera and I've found it to be an astounding lens for indoor sports like basketball as long as you can get to court side being that it obviously doesn't have a great deal of reach.
It works quite well for night time outdoor sports like HS football also, again assuming you can get to the sidelines.
Of all the Nikkor glass I own, and it's enough to buy a decent car, the 1.8 AF is IMHO the ne plus ultra of value.
I do wish the lens had metal construction ... but then it would cost a lot more, and at this price point it wouldn't hurt too much is you broke one.
That's not to imply that it's fragile either because mine is closing in on 20 years of age (Bought it in 1991/92 ish.) and I have probably shot at least 5,000 shots with it over time.
It honestly is typical Nikkor indestructible but has always had a flimsier feel to it than other Nikkors ... owners will know what I mean.
Similar to the new G kit lenses in that aspect and probably because it was the kit lens for years itself.
