what lcd screens can i use?

what is a list of lcd screens i can use? can i use a gameboy advance screen? where are some places i can get some cheap ones?

There is a list of libraries with supported chips on the Playground (look at Graphics LCD): http://arduino.cc/playground/Code/LCD

It might be a good starting point.

Cheap LCDs could be extraced from some old mobile phones (zero cost... :D)

Do you have a project in mind that uses an LCD?

a lcd that reads off the the html of a specific page with only a couple values.
