I paid 120 bucks for mine and its worked great for 2 years and 4 months, and calibration out of the box was almost perfect.
Of those two you linked i definitely suggest the hanns-g one, you definitely want to buy a 1920x1080 screen and not 1600x900 for various reasons.

Wait i see why its so cheap now, it does not come with a DVI cable. This isnt a huge deal because you may have one lying around and if you need to buy one they are not that expensive. Just explains why its so cheap.
