This one is great, but pricey. And, doesn't ship to the US. Two strikes.
Sometimes you can find great stuff in the teen section - like this Darby task lamp from RH Teen.

From West Elem, the Scoop is delicate and not visually obtrusive.
And this one, sadly also from England. Oh, and sold out. Love the design, though.
