There are loads of more-or-less battered Courieresque free fonts knocking about on the Net, many of which I&#039;ve grabbed. As a screenwriter (and you should *see* the amount of font fetishism on screenwriting forums), Courier&#039;s mandatory for screenplays but fiddling with fonts for the copious amount of treatmenting and synopsising I do is always a great procrastination tool.  Even so, I&#039;ve managed to use Courier 10BT for scripts. It&#039;s a bit heavier than Courier New, and non proportional. 
 
My default in Scriv at the moment is Lucida Typewriter, which is sans and based on one of those Selectricish typewriter fonts.
