I'm finally heading off to grad school and thought that, with the poor economy and holiday sales approaching, the next few weeks would be a rather good time to make my first HD TV purchase. I was looking for something 40-47 inches in the following price categories: $900 and under $800 and under $700 and under Which do you feel would be the best choice and where might I find it? Keep in mind that I wont have HD cable and own an original X-Box/Playstation 2 that I would like to continue using, so SD quality is important as well. At this size, would 1080p be recommended, or will there be no difference? Do you recommend an extended warranty? If anyone had any tips on finding a good deal that would be great as well. Thank you!
