The ERM2004GS-1 LCD module for Arduino features a 20x4 character dark-blue on while/light-grey display, 5v power and a parallel interface. They are made for us by a major LCD manufacturer for our Panelolu2 and PanelOne LCD controllers, but are also suitable for many other projects.

The LCD module features both top and bottom 16-way connectors (see images) making it more versatile than most other 20x4 LCDs with top connectors only. LCDs are factory-tested and supplied in an antistatic bag.
