No, I haven't seen that many reviews on the Iiyama either. A lot of owner reviews but no professional ones.
I'm not so sure about that 172x anymore. There is a lot of discussion going on whether it is indeed such a good display as the specs will want you to believe.
That EIZO confuses me a bit in its ergonomics. I wonder whether I need an additional stand for this display or not.
Another contender has entered the room though: NEC's LDC1760.
Damn, I wished Hercules would change their mind :>(
