I found some great deals with some special codes for those that are interested. These deals are direct from XM and Sirius, so no I am not a vendor. I have both, so I have no axe to grind there either. Just wanted to pass along some info:
XM has 2 stationary satellites and about 1400 ground repeaters; Sirius has 3 satellites that move and about 400 ground repeaters. Sirius satellites are higher and provide a better signal in rural areas because of the angle. XM gets better indoor signals because they have more ground repeaters.
Either way you go, it is way better than FM. I suggest you go to www.sirius.com and www.xmradio.com and look around, you can listen to each online for free for 3 days.
XM is $9.95 a month, plus $1.99 to get Opie and Anthony, plus $2.99 for Playboy, plus $3.99 for online web streaming, MLB and NASCAR are included
Sirius is $12.95, includes Howard Stern (Jan 06), includes Maxim Radio, includes FREE web streaming, includes all the NFL Games (both home and away broadcast teams), The NBA, The NHL, and College Sports.
Additional subsciptions (2-4) are $6.99 more on each.
Sirius has a $499 lifetime plan if you want to do that, not many people do.
What one is for me?
I would listen to both on line for 3 days and see what you think. Understand that neither stream very much of the talk lineups.
