Hi Gary -
I got a new monitor last year, and opted for an HP 24yh. I like it quite a bit for photography work, as it's an IPS display. When I was researching monitors before my purchase I was not aware of the different panel types, and reading about them everyone seemed to agree that IPS is the way to go for color fidelity and greatest viewing angle. I certainly noticed a difference when I set mine up next to my old monitor.
I don't know what other brands are out there offhand, but I can tell you I saw a lot of YouTube videos on the subject of "Best Monitor". You might want to cruise around there and see what the current crop of reviews have to say about units in your price range.
Good hunting!
