I bought a few about a year ago from a surplus electronics store on the
web.
I can't remember the name, but I have links ot about 10 at
www.homeautomationindex.com. Look for the "Electronic
Components" section.
What I bought had a keypad (0-9 and 2 others) and an LCD and a 9 pin serial
cable. It runs at 9600 baud and you just send text to it to be displayed.
When a button is pressed, the character for that button is sent out the
serial port. Very easy to interface to. It even accepts some control
characters to clear the screen and a few other things.
The keypad/lcd wasn't pretty, you'd have to make an enclosure for it.
I think each unit cost $9. So, if this is what you are looking for, check
the surplus electronic sites for something.
