Initial investment in satellite radio averages from $100 to $150. This will buy a receiver and a docking station for hooking it into an existing home unit or your car. You can also buy a boombox for about $100, but you do not have the flexibility of listening through your car or home stereo in that case.

I have a receiver, car unit and a boombox. With installation of the car unit (which I did not want to try to install on my own) I spent about $200.   The fee for monthly service is $10.   Additional units would be separate purchases and require additional monthly fees at a special rate.

This may be too expensive for some people, and that is understandable.   Like cable television, this is a luxury item. You get variety of programming, most channels are commercial free, the audio is better than FM signals, and it is fun. My unit also gives me a stock ticker and sports ticker option.   I love it and find it to be worth every penny. I will probably purchase units for my wife and daughter this year.
