I've just ordered another of this monitor. Seems like a good deal for a 24" LED HD (1920x1080) monitor delivered.
I ordered one last week with the same coupon, and received the screen on Friday. Very happy with it. Now they have it $50 cheaper to begin with aswell. Nice energy efficient screen (uses ~20W).
I love my Dell 24" LCD (E248WFP) - using monitors under 22" feels strange now :)
