there are several LCD options for you to choose from. there are big ones (40x4, 20x4, etc.) there are also little ones (16x2, etc.)
do you want it backlit? (costs a bit more)
get them from places like eio.com, timeline.com, mpja.com.....
for those, you'll need to solder your serial or LPT connections from the cable to the display..
some people offer pre-built LCD's..
(Inmotion, Lorty, etc..)
(prebuilt=$$$$$) obviously if you hook the suckers up yourself, it's cheaper.
do some archive searches on this board.
...as always, that will help immensely...
