My housemate just bought the Hyundai. (£215 elsewhere i think). It's a beautiful monitor, one of the best looking 19" i've seen. There is no DVI.
If you are are stepping up from a 17, bear in mind that there will be no increase in resolution, so things will just be bigger, you won't gain any more windows space..
A 20" would help you keep a similar dpi to a 17". I too have been considering one of these for a while. It can be had as low as £265. But i've decided a snowboarding holuday must come first
