What you need to hear Sirius

You can find these receivers at just about any electronics retailer such as Best Buy and Circuit City, as well as online at Crutchfield.com, Amazon.com, and TechforLess. The price of these receivers vary all over the place. Some are Sirius ready, meaning that they play through your car radio's CD or cassette player, while others are Sirius portable and can be moved from the car to your home.

A subscription to Sirius currently costs $12.95 per month or about $155 a year.

The downside

There are a few things to consider before buying a Sirius radio. For one thing, it's never local. In other words, you will never hear local weather, local sports updates, local talk radio or local traffic conditions.

Second, you need to consider how much time you spend in your care. If you spend 3 to 4 hours per day driving around, Sirius might be worth the cost. However, if you're in your car only an hour or less a day, you might not want to spend $155 a year to hear commercial-free music, etc.

Finally, there is no guarantee that those commercial-free channels will stay commercial free forever. Sirius continues to lose money as a subscription-based service, and may eventually have to start charging extra for some of its more popular channels.
