I'm looking to get an HDTV and wanted opinions. I'd love to spend around $800, however I can go up to $3500 if it's worth it in the long run. Price range: $800 - $3500. Uses: HD Gaming and HD-DVD/Blu-Ray exclusively, although if SD channels look better on an HDTV I might watch TV on it too. Size: I'll be sitting 5 feet away from it. Someone told me not to go below 40". Is 37" acceptable at that distance? What's the difference between plasma, projection TV, DLP, and LCD HDTVs? I don't want to worry about burn in (is Plasma the one that suffers from burn in?). I want something thin. Thanks! Is this a good TV? http://www.bestbuy.com/site/olspage....=1169512521206 Right around 2k after tax and service plan.
