I'm buying a monitor soon, and have found a few LCD ones that I like. However, I have also found some LED ones which are more expensive, and I'm wondering if it's worth spending the extra 50-ish on an LED display. I'm going to be mainly using it for movies and productivity stuff (iWork, web, email, etc). Also, would anyone have any recommendations (LCD or LED) for 20" - 24", around 250 - 300 ($350 - $400)? Thanks!
