My mother-in-law was visiting recently and while she was in NY, she stopped in at the MOMA Design Store and picked up these awesome Nested Prep/Measuring Bowls as a gift for me. The orange melamine bowls are designed by Mario Batali (what can't that guy do?!) and inside have lines for measuring. So you can use them for prep, or measuring cups, or both! Handy dandy, and beautiful to boot.
