I would recommend stepping up just a bit to the Panasonic TC-P60ST50 60-Inch plasma. Panasonic offers a very high level of quality for the money as well as a great image. I like my Samsung, but I feel like their cheaper displays really start to lose overall image quality and product build quality.
I will flat out never tell anyone to get an LG. I think their image generally looks good but their built quality is non-existent. I personally know several people who have had LG displays fail on them, and many more with similar complainst online. They have a reported failure rate which is four times higher than Panasonic. So, you gamble on LG every single time and that's not what I would consider money worth gambling.
