Displays ViewSonic VP2365 LED or Benq EW2430?

i've got about £200 to spend on a new monitor, which i'll be using primarily for reviewing and editing photographs and doing graphics work on and possibly video work as well. i'm not really that interested in gaming or watching movies on the pc.

i was thinking of either the ViewSonic VP2365 LED or the Benq EW2430. does anyone have experience of either or both of these monitors, and which would you recommend, bearing in mind they use different panels? i assume the ViewSonic has more accurate colour, but doesn't appear to have as much contrast. any views? any help much appreciated.
