For the money, I've used both of these and both are excellent with viewing angles and colour reproduction. Both are IPS and feature higher than usual resolutions.
The extra resolution is a must, and these both calibrate for very, very accurate colour.
The Dell 29" wide wide monitor $529. 2560 x 1080 resolution.

I prefer the Kogan for photo editing, and the Dell for video work.
