I already have Sirius and I’m very happy with it.
I got the S50, which can do everything the new one can, except get the satelite reception without an antenna (I know, that’s a big “except”, but it can download songs from Sirius for use as a portable player, and you can download your own mp3s to it).
The S50 was $300, but came with a $100 mail in rebate, which I took advantage of.
At first I didn’t think I’d listen to Howard that often, and I bought it mostly for the comercial free music, and partly for Howard, but then I got hooked on his show.
It’s absolutely great IMO, and better than I remember it from when he was on regular radio.
I’m in my van for an average of 3 hours a day, 4-5 days a week, so it’s really worth every penny for me.
