Small low powered, E-INK or bistable LCD display

Hey guys,

Does anyone have any experience or know of a good, small cheap E-INK type display? Or maybe just a display that is bi-stable and holds the image when unpowered.

I've thought of a ultra low powered project that uses very little power and visually displays the information. it could be a simple hd44780 type but I cant really find anything perfect.

Someone was just asking about this recently: Super low power screen.
