lcd 17" for a gamer

[Icone]

I'm looking for a new LCD screen for my pc because my old one (lg 776fm) is dead.

The problem is that i have to chose one of these three and obviously, i dont know what to do

LG 1780Q
ViewSonic VP171-B/S
Samsung 730B

As u see, all these screens have 8ms response time (gamer).
I saw the LG next to the Samsung 710T and i was disappointed from his sharpness and it was kind of dark to me... so i'm leaning towards the Viewsonic/Samsung and i have a few questions.

1. The Samsung has the lowest price 300-350$ while the ViewSonic is 450-500$ (LG too).
Why does the Samsung is so "cheap"? is it an old model or something? or is it in other class from the LG and the ViewSonic?

2. The Samsung offers 600:1 contrast while the ViewSonic offers 500:1, does it matter? does it effect the image quallity?

3. What screen in your opinion has "better" image quallity? what screen do you prefer?

by the way, i'm from IL so my english sux.. so...

I just got my Samsung 30B for $250 after rebates, and I love it! It's so bright and sharp, I run it on DVI. The picture is really nice, and I don't have any dead pixels or backlight bleeding.

Are those figures in Canadian money? Newegg has the 171B for way less than 450.

330 with shipping.

Newegg doesn't carry the 730b currently, so no direct price comparasion

Got my 730B at Circuit City. 8ms response, DVI and VGA, nice looking, what more could I want? It looks amazing in every game, and doesn't have any ghosting or dead pixels.
