I am very surprised.

Controlling a decent sized LCD is not an unusual 
thing to do -- why are there no cheap solutions??

Has anyone had any luck with the RA8835 
chip?  It's supposed to be a drop-in replacement 
for the SED1335 but I can't figure out where to buy it!

The Freescale MC908 looks like it might work as 
well, except I can't find any documentation on it 
and the freescale site is very broken.

There must be another way...
