What's the difference between Sony KV-32HS500 and Sony KV-32HV600. They are both HD TV's, 32 inches, yet one is $200 more than the other. What should I be paying for either set? The retail prices are $1499 and 1699. Thanks. While we are on the topic, what is the difference between Sony KV-36HS500 and Sony KV-36XBR800. How come there is not an XBR800 for the 32 inch version when they had a 32 inch XBR last year? Any help will be greatly appreciated. Thanks!!
