Fry's has a great one on sale for the next two days:
Asus PG278Q G-Sync 27" LED Monitor,2560x1440Resolution,144hz Refresh
http://www.frys.com/product/8237286?site=cemail070716
for $579, reg $699.
About the only thing I use these days that is Dell is my monitor on the main.
They do monitors pretty well IMHO, have a widescreen IPS.
The one stuck pixel I do have is on the far left of the screen in dark grey, I don't even notice it unless I think about it really, it's on the edge.
Is just a older 2560 x 1080, but I've been happy with it a few years now.
