DealExtreme is getting into building DIY projects these days and the number of Arduino compatible sensors / equipments is rapidly increasing on their website with free shipping all around the world.
This time I have found some useful libraries for the LCD + Keypad they sell which could be bought from this link.
You could first prepare the library for the component. There are some libraries that are designed for some components very similar to the one sold on DX. You can find a tutorial on this website how to customize them to fit new Arudino (see here).
The code example for writing on LCD
LCD4Bit_mod lcd = LCD4Bit_mod(2);
int counter = 0;
itoa(counter, counterStr, 10);
