I'm looking to add an Airport Express to my home theater setup, but I don't really want to pay the hundred bucks... it's certainly not worth that. Is there another device that has the same functionality of the airport express?
airtunes - Not as cleanly, and not directly from the itunes window, but there is airfoil which will let you send any audio from a mac or pc to mac, pc, linux, iphone, or ipod touch. Or the TV, but that's not less $
