I strongly recommend the seemingly sketchy Korean monitors as well. They were all the rage a few months ago when folks at Overclock discovered them. I personally own both an ATD and a 27" Shimian tempered glass model and I find the displays in both to be comparable. I don't regret my ATD since it does have the Thunderbolt dock and all, and it is a great deal compared to competitors like Dell, but really, had I know about these beforehand, I wouldn't have bought it. $300 shipped vs $900 is just too tremendous of a value when the IQ is about the same.
Also, I did not specifically pay for a no dead pixel one, but mine came out perfect with none. It does seem to have a few dust specs underneath the glass, but this is apparently common for these models. Nonetheless, they're really just an incredible steal.
Just note that it requires dual-link DVI so you can't just use a miniDP to DVI adapter; you need an active one to upconvert the signal and that will cost around $50 and consume another USB port as well.
