Hi colin

Ignore the futurlec info...i think its the wrong display anyway. I 
hunted and hunted and have found this 
http://www.onestopdisplays.net/OSD1602.php here in melbourne which 
is the same as the crystalfonts unit in every way i can see....and 
at $25au its even cheaper than crystalfonts ;)

Cant wait looks like my P3 will be up and running this weekend!!!
