I just got a Sony SDM-HS95P/S and that is about the sharpest screen I have ever seen and you can get that for 599.99 with mail in.
I have not seen the Dell in action yet so I cant compare but I will say the Sony has a better picture that a regular CRT mine being a Dell 780
And Im not even a Sony fan.
