The problem with the Sony V is that it's very stingy on the inputs; no VGA on a screen that price is ridiculous in my opinion.
Only buy a HD screen if that will be your primary use. If the majority of the television's use with be SDTV, buy a Sharp P50. It's compatible with HD, and will still look great with it, but is the best looking LCD out there for SD content. (regular television, DVDs etc)
