New to meida streaming, here's what I'd like to do. I'd like to be able to wirelessly stream mp3's from iTunes on my PC (windows xp, always on) and internet radio (xm radio online) to my a/v receiver.

I'm not interested in streaming video, only audio. I'd like to be able to have some sort of on-screen guide for what I'm accessing from my computer on my TV screen. I'll be using a Logitech Harmony to control everything.

Budget - somewhere between $100-$200 - the cheaper the better. Thanks!
