I have had the samsung BX2450 for about a month now. I am completely happy with it and can't find any faults.
I went with samsung as I have a few friends that have used em for tvs/monitors and all are completely happy with the brand.
The 2ms response, hdmi, and other features along with the LED backlight made me buy it even though I bought it in between the sale price and paid £35 extra. I just couldn't find anything to beat it at the price range it was at.
