I'd like to get a decent sized graphic display ...
This is my favorite:

This 128x64 LCD works with a single 5V supply and comes with a prefitted 4-wire touchscreen. The combination of LCD/touchscreen is good for prototype/one-off designs (no keypad needed). You get 8 lines with 21 characters (5x7) or 6 lines of text plus 4 large (good-to-push) buttons.
Add a top plate of brushed aluminium with a cutout for the display area and the finished project looks excellent and works well.
