Now that I am listening to more and more AM radio (There's a thought, a 15 year old listening to AM radio, but I like it) because of a few talk shows, I want to get a radio tuner for my iBook so I can record the shows and listen to them later. The only option I'm seeing for the Mac is Griffin's radioSHARK 2, which is backordered. I want to know, has anybody used one of these? How's the reception? Do you get signal noise in places you do with your current radio? Also, I'm assuming there are no HD Radio tuners out there yet, right? That's what I would really like, but I don't think there are any out there yet.
