I used to have this cheesy "boombox" style radio-slash-CD-player in the garage, of which I made heavy use during the construction of the empennage kit. It was great, except for the fact that it refused to play most of my CDs, and it could really only pick up radio stations if I was standing right next to it. Okay, it actually sucked. But those days are over now!
I replaced the cheesy boombox with an Airport Express that I picked up for cheap (factory refurb deal) and a spare set of computer speakers I had laying around. Now I can wirelessly pipe CDs, mp3s, and streaming audio out to the garage, and the sound quality is excellent. I can even use the computer upstairs to tune into local radio stations' streaming internet feeds and beam them out to the airplane workshop in full digital glory – a roundabout and absurdly complicated way to listen to the radio, to be sure, but a satisfying one nonetheless.
