Searching for a small hi-res monochrome lcd (about 256x64px)

Hi all,

I am searching for a small high resolution monochrome LCD.

The outline measurements and the resolution should be likte this OLED display: http://www.buydisplay.com/default/serial-3-2-inch-display-arduino-256x64-oled-screen-module-white-on-black

... But as monochrome LCD because of energy consumption and contrast in the sunlight.

The only thing i found yet was this one (which is a little bit too big and very expensive): http://www.mouser.at/ProductDetail/ELECTRONIC-ASSEMBLY/EA-DOGM240W-6/?qs=sGAEpiMZZMvkC18yXH9iIrD81%2bNGm8W9DFs803F2digzd%2b4QB2w5Og%3D%3D

I am searching for a few days now, but can't find a display that fits my needs (size, resolution, cheap). Communication should be SPI.

Maybe someone here can help me.

Thanks a lot!

Cheers
