The "safe", well-regarded brands are Eizo and NEC. Yes, their top of the line models are out of reach for most normal incomes, but they have affordable lines as well. The advantage is that they already have their quality control set up to meet high standards, and they have a reputation to protect.
The one basic requirement is an IPS panel. Don't consider anything else.
Wide gamut will cost you. You probably don't need it. I have a wide gamut Eizo at work, because I need it there, but at home I have standard gamut and I'm perfectly happy with that.
Other than that it's difficult to make specific recommendations. You should ideally try it before you buy, preferably at home. The sad fact is that you don't always get what you pay for, mostly due to sloppy QC.
Personal experience: A couple of years ago I bought a Dell U2410, which is a "bargain high end" model with very high specifications on paper. When I got it it turned out to be completely useless, with one side of the screen cyanish and the other side magenta-pinkish. Not what I expected, to say the least. Long story short, it turned out that a lot of people had gotten these turkeys, and Dell's official response was to declare it "within specification". Tough luck.
Now, I'm sure most U2410s (and present U2413s) are perfectly fine. And I'm sure it's not only Dell. But this is the sort of thing that can happen, and that's why you should look more at QC than specifications, and try it at home if possible.
