So, I have Rush 24x7 and it works fine for me.
Bosco -- you don't have to give up your AM/FM to get satellite. It's just an add-on. So you can still have Rush.
I have a usb computer version in the house and a Roady in the car. I love it. If there is a big story breaking on fox and I have to go somewhere then I turn it on in the car. Awesome. And no commercials on the music channels (there are commercials on the tv channels but are generally self-promotion)
I'll never forget the day I got the XM. I was in my car listening to Rush on the local am channel. Suddenly, Rush was cut and the Red Sox pre-game started. Although this was nothing new because the same station had consolidated two am stations into one, it was never announced ahead of time. Then, during the first commercial break, the am station had a self promotion on how one should stay away from satellite radio and all the supposed downfalls. I yelled out, "How about the downside when you are listening to a show that discusses real issues and all of sudden...gone?!" I love the sox but because the local station tried to put all their eggs in one basket, now some of their loyal listeners would have Rush cut short almost every other day. I was pissed.
It was right then that I decided to get one for the car too. I've got Rush 24/7 so I now listen to Laura Ingraham's show then Rush later. It's awesome
