If you're worried about glare and reflection, get the flat screen, if not, go for the 19". Personally, I like my 17" Trinitron flat better than most non-flat 19" monitors I've seen. If you're going to an actual store, look at the monitors and compare the pictures. Ask them to hook it up to a display PC to get an actual idea of the image quality. Also, open-box monitors can be a steal.
