Go cruise around newegg some I found
this one there just with a quick search sorted by price low-high.
And like Landrell said, you really can't go wrong with Asus. They put out some quality stuff.
Don't over look Acer either. They may not be the top of the line but they've come a long way since they first showed up a few years back. My monitor is an emachines 23" 1920x1080 and I have zero complaints, I think I paid in the neighborhood of 150 for it new a few months back.
