Earvana nut?

Has anyone here used one of these?

I was thinking of having one installed on my 360.

Any thoughts?

I have heard good reviews on them, they're supposed to work well. But do they come in black?
I've changed my nut on all of my guitars to bone, which I think is the best material for a nut. All of them except for my Rics...
I think a white nut would look too weird on a Ric, plus the tone and sustain are already there from whatever material they put on at the factory.
Bakelite maybe?
