The Dell 29" version is $529 which seems a good deal. Same panel as the LG apparently, and has a USB3 hub built in.

The only thing with all of these monitors is they are kind of smaller than you would expect, the 29" is a diagonal measurement so the actual screen size is about 28cm high, which is less than a 19" 4:3 monitor.
Of course, the screen area is about 67cm long, which is l-o-v-e-l-y.
