The best TFT is one with a DVI connection, if your graphics card has DVI out then go for that. The difference between analogue TFT and DVI TFT output is quite different (Vinyl to CD, VHS to DVD if you know what I mean) yes you can get cheap TFT's but they are mostly analogue the better ones are most definately DVI. This will make full use of your DVI graphics card, depends what you need it for at the end of the day.
