OneStopDisplays is making drop-in replacements for some of the Osram
models.
I used one of the color 128x128 OLEDs for a while but found that the
blue didn't last very long. The fading was noticable after less than a
month. Today's AMOLEDs are supposed to be better about that, though.
If you were thinking monochrome before, color rocks!

sells some nice graphic and TFT
displays (low quantity okay). http://www.trulysemi.com/
is another
place. I was a little skeptical about TFT displays because they used
to be pricey, but with some shopping around I found that a 2.4" QVGA
could be had for $14 in 10K quantity. The cheap little 128x128 CLCDs
you see in small cell phones go for something like $4.
I assume you're taking advantage of the window address function. For
example, if you have to put a 5x8 character on the screen, set the
window rows/columns (to form a 5x8 rectanglular field) and blast the
display with 40 pixels of data. No frame buffer required.
