Current for both stations here -- a couple of 8 year-old Apple Cinema Displays. Paid for. Long ago.
The older one has some significant backlight issues... big blotches around the edge of screen. So I have some cheapy Samsungs floating around in case that one croaks at some inopportune moment. Meanwhile I use one of them for GranTurismo 6... and reviewing BluRay burns... on my PS3.... yeah, that's why I have one of those. That's my story.
My third station, at a shared-space location, owner there insisted on a couple of LaCie something-or-others to maintain a decor directive. As far as the GUI is concerned, all I see is a lot of numbers and words, okay, some thumbnails, but almost totally irrelevant in the sense of aesthetics. And the fact that their edit suite is one-make, all LaCie, all the monitors look the same, and on that issue --> Flanders for grade, the same as at my home-base studio.
At first I had to wonder about "monitor recommendations"... because that topic is just a minefield, but you seem to be more interested in a graphic display, so really, anything that isn't going to detract too much from your real reference monitor -- I'd be careful with size, because with it comes the baggage of eye-strain, ergonomics and the overall contribution to poisoning your grade environment with a ton of wrong-temperature ambient light.
