dont bother with the B/W laptop screen, I would bet that it would be cheaper and less heartache in the long run to fork out for a colour LCD in the long run..... since you will want to play DVD's/DivX oneday and regret the time spent on a B/W lcd.....
.....but personally I have a 40X2 LCD (check my site for images) and I love it.... they are cheap to buy even in AUS (I know of a few surplus suppliers) and once you get one wired up they are a piece of cake to get going......
my ideas and ramblings anyway.....
