I bought my first LCD last spring, a square 19". I looove it! Very crisp, bright, and works flawlessly for games, even fast-paced shooters. It's a
19-inch Samsung 931B.
It let me reclaim a lot of desktop space, and the whole desk looks cleaner. I considered a 21" or 24" but decided to go with the 19"., it's just the perfect size for a screen that is only 16 inches from my face... and $169, very good deal.
