I would try hardforum.com, this forum in particular
http://hardforum.com/forumdisplay.php?f=78 to make a solid, informed decision. Problem with displays is you'll end up with a hundred recommendations from people who don't know what they're talking about. Brandwise, I know Asus and Dell are very popular and Asus displays are typically geared toward enthusiast gamers on a budget and get great reviews from people who have purchased them.
