My immediate recommendation, based on this, would be the BenQ V2400 ECO or G2420HDBL (if you're looking for a 24" screen). As with all TN panels, the colours aren't as accurate as they could be - but you will find the image pleasing, vibrant and more than accurate enough for gaming and movies. There are lots of happy users of this monitor on the forums, it seems. I haven't tried it myself so I can't wholeheartedly recommend it, but have a read and see what you think.
And incase you're wondering - the V2400 ECO is essentially the same panel, with HDMI connectivity and a slightly different look.
