Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
If you're happy with 720 let me give you a piece of advise that will save you a ton of money - buy an upconvertion dvd player and buy DVDs - saves you a ton of money on the player and tons more on media and still looks decent.
There's nothing all that wrong with being happy with a 720 picture (hell we've all had worse for most of our lives), but don't come and tell me it's right for a brand new product to incorporate a blu-ray on a 720 display. It's sort of like buying a ferrari engine and putting it in a kia.
