ZDNet has a lot of hardware reviews, too, if you browse through their reviews section. Since they're the publisher of many magazines, they'll link you to reviews in all their publications, including PC Magazine, Computer Shopper, etc. PC World also has a lot of reviews for monitors and other retail hardware. To a lesser extent, you can always try and check the manufacturers' websites. A lot of times they link to positive reviews of their products, which do nothing but make you feel better about your purchase, but at least then you know you're reading from a site that reviews monitors and you can see what else they have looked at.
As for reviews being up to date, I wouldn't worry when it comes to monitors. A monitor that's crisp and clear two years ago will still be crisp and clear today if it's new in the box.
