Looking for a speaker and wondering whether 'tis better to buy one AirPlay enabled or just plug an AirPort Express into a non-AP-enabled one. The latter's cheaper, I believe? Need something that can be plugged in for power (i.e. don't wanna be bothered with recharging or replacing batteries).

...Actually, I think I also need to be able to send the same signal to speakers in mulitple rooms.

Anyone?... Anyone?... Bueller?
