I've been thinking of getting the
ASUS VW246H (same one Learux mentioned) when I build a new comp soon. I've been saying I'll build a new comp "soon" for over half a year now, but my current desktop is really starting to tick me off with some problems it's having so I'm closer now than I've been for a while.
5 star rating on the above monitor on Newegg, with 931 reviews. Not bad.
This one that OS-Wiz recommended on the first page looks pretty decent too, though, and I've always had a lot of success with Samsung TVs and monitors.
