I'll second the GLCD suggestion as long as you can't deal with the regular character LCD limitations.

Sure PBP command set don't support any GLCD type. You'll need to create your own GLCD driver. Sure it's not a really easy task, but once you have it, the whole thing look by far better than a simple character type LCD.
