I believe this is the most bang for your buck or the one below...
It also depends if u have a tv tuner or even plan on using it at any point as a television.
those are popular or looked good to me, only checked newegg so prices may be slightly lower if at all elsewhere. Search the models if you are interested for specs.
don't forget about craigslist! I bought a 32inch 1080 for 150$, ppl constantly steal stuff like that and want quick cash, so catch them when their desperate! lol. other than that just keep checking newegg, tigerdirect, amazon, and checkout Techbargains.com <-- has some really awesome *** like everyday.
