Don't know anything about Sirius but I do own XM for my Motorhome and pickup. I also just bought the portable unit for my wifes suburban. We got the optional boom box so that we can remove the one out of her Sub and plug it into the boom box and take it anywhere. We love it. You get addicted to the great music and no commercials.

I would assume Sirius is similar.

Bubba is signing a deal with Sirius to broadcast his show in sat. I don't have sat radio but I do own sirius stock.....Dave

I own both Sirius and XM, and here is my opinion. The sound quality of the Sirius is much better than the sound quality of the XM, but only on the music channels. On the talk channels, the sound quality of XM is better. I believe that Sirius uses more bandwidth for their music channels, which takes away bandwidth from their talk stations. The programming between the two is personal choice. I prefer the programming on Sirius over XM, but other’s tastes may differ. Sirius uses 3 satellites, versus XM has 2. It might not make a difference to most, but I live in the mountains, and while loosing a signal is very infrequent, it happens more on the XM than on the Sirius.

I would not worry about the financials of Sirius. Chances are that they will be bought out before going off air.

Thanks for all the info! I still dont know what one to buy!

I just recently researched all this as well, and was surprised at how many accessories were required after purchasing a "satellite radio ready" in deck stereo for my truck. My initial inclination was to go with Sirius, because it offered both OLN and The Speed Network, which would be a perk for listening to racing broadcasts. The bigger companies (ie: Circuit City, Best Buy, etc...) offer a free receiver for some of their Sirius ready decks. The installation for the box, under the seat is almost more than the box itself, so take the free parts where you can get them. Not to mention docking units, antennas, FM Modulators, etc...

However, after researching on customer satsifaction, company growth, etc.... as well as what car stereo brands are XM or Sirius ready, I ended up going with XM because I wanted a Pioneer stereo for my car, and I think, from what I've been able to listen to, XM had better sound quality.

Just my two cents on the subject........
