New TV maybe - SP

So I'm thinking about buying a new TV so I'm always on the lookout for good tv deals. Though I don't think that place will apply to me. I don't actually watch a lot of TV anymore, the more I blog the less I watch and I'm finding I can entertain myself just fine watching videos on the net. So why would I want an HD TV, well I'm thinking about getting a PS3 and you need HD to play that machine with.
