Second do not get a 19". AFAIK, all 19" are still 1280*1024, the largest pixels of any standard LCD display.
A good 20" @1600*1200 will be fine. I like my dual Samsung 204T's at work. I've got them running at 20% brightness. Some LCD's I've seen are always too bright.
Pay attention to your room/task lighting too. Eyestrain is caused by a combination of the room/monitor.
