The SW271C is an excellent monitor. It's a near ideal combination of size and performance for image editing work, presented in an elegant and well thought out package.
It has nudged up noticeably in price over the previous model, but the reality is even at the new price point it offers excellent value for professional and serious amateur visual artists alike.
To get anything better, you have to spend about $800 more for Eizo's CS2740 + Hood. That is ultimately a better, more refined monitor package (particularly the software), and has a five year warranty, compared to three, with the BenQ. But it's also well on the way to a thousand dollars more expensive - so it would want to be! And it's not drastically better, at all. No, in the quality race, the SW271C is nipping at Eizo's heels.
