Monitors are half the price and give a better picture, but take up a bigger footprint. Monitors are also flexible in giving a good picture at various settings whilst LCDs are lousy at anything apart from their normal resolution, normally 1024x768 for 15" and 1280x1024 for 17". Your video should support both so, if you set the resolution before changing over, it will simply be a matter of unplugging one and plugging in the other.
Personally I have a Philips 15" and a new Samsung (191T) 19", but I'm a flash g*t with money to spare.
The best selling model at Jungle is not one I've heard of, but it has over 40 good reviews and is, relatively, cheap.
