The actual screen itself is the same screen that Apple put in their cinema displays (2560x1440 IPS, etc) but it's over half the price. There are a few downsides though: the monitor case isn't as nice as the aluminium cinema display, though IMO is still pretty good. Also the sound quality of the built-in speakers is pretty terrible. Still, you could buy an amazing set of speakers and still have change left from a cinema display budget :-)
I like the site so far, one of the things that annoyed me is when your choosing to buy or sell a house. You should add a hover effect so the user knows what they're about to click.
