I first tried Sirius Satellite Radio about 3 years ago. I became interested in it shortly after I purchased a new car in 2005 but of course, at that time, it was rare for cars to come equiped with a receiver so I purchased an after market car kit and rigged it into my car. It actually works out quite nice as I took the ashtray out and it fits perfectly in that spot! My first reciever burned out. I guess I must have used it too much! But after having satellite radio for two years, I couldn't give it up! I ran out and purchased another receiver. This one is the Sirius Roadster. There was no option to purchase a receiver by itself so I ended up with a second car kit. It actually comes in handy because we can now easily switch the receiver to my husbands car without messing with the car kit that is fairly permanent in my car right now. I love the service so much that I also purchased a home kit for the Roadster receiver. When traveling, it is so nice not to have to try to find a decent radio station every 100 miles or so. We have a choice of well over 120 stations to listen too and we never lose a signal - except in tunnels or gas stations (overhangs block the signal!).
I highly recommend Sirus and the Roadster receiver for anyone who loves commercial free programing and a constant signal!
