Wait for the AF-S 50mm 1.4 to be realeased in the coming months, i was anounced last week. Unlike the current 1.4 and 1.8 it will give you full AF function. Both current 50's will not give AF with D60 but will give an indication of focus through the electronic rangefinder, up to F5.6

With regard to people harping on about how beneficial a 50mm can be to the developement of someones skill i think the main thing they are relating to is that due to the fixed nature of the lens, it does to some extent force to put more thought into your composition, that you would possibly not with a zoom lens...
