Why don't you make your own bokeh? Get some paper, scissors, and shoot in evening in any major city.
I like Nikon's 50mm f/1.4 and f/1.8, the latter is much less expensive. These would be fine for the D60.
Although I am not certain if the D60 has an AF motor, if not you will have to manually focus.
I am a fan of the cream machine, 85mm f/1.4, grab a sharp copy and you cannot go wrong.
If you have a few extra $ and are very comfortable with your camera, get some Zeiss glass. It is a hefty investment but if you can afford it, do it.
