If you want to stay with another with the glossy screen so it matches the Gateway 2401 is decent - I've used a couple of them and like them (I prefer the glossy screen )
I've had a Dell 20" 2005FPW display for the past 3 years and I've been extremely satisfied with it. Assuming their quality is still on par with the display I picked up 3 years ago, you can't go wrong for the price.
