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!"
This is just a pointless story ....
I can walk into a store today and buy HD-DVD's - it'll be over a month before I can say the same for Blu-ray. How can something thats not available be cheaper?
Anyway, even at a few bucks less per disc, it will take you a long while to re-coup the difference in the cost of your early adopter player.
