Tasteful, intelligent control layout and an excellent display make the Sportster a pleasure to use. A socket on the bottom edge plugs into a home or car cradle (each sold separately with appropriate power supply and antenna for $50) or other compatible device, such as the Sportster Boombox ($100). The Sportster's hot feature is called Game Alert. Enter your favorite NFL and NHL teams into memory, and the radio will automatically alert you when they're playing and give you the option of tuning to the appropriate channel. Since Sirius carries every game played, football fans never have to miss out. You can also program the radio to switch to a particular channel at a particular time.
