from what i've read...XM is already available and is about $10/month..they use 2 satellites. some Pioneer head units are XM satellite ready so you get the Digital sound and don't have to use a FM converter.
Sirius will be ready for the beginning of next year and its going to run 12-13/month but they use 3 satellites. some Kennwood head units are coming Sirius satellite ready
when you guys start using it..let me know how you like it.
I'm definately going to look into getting it cause the radio stations here in Pittsburgh suck...but only if i get a new head unit that is satellite ready, cause if you use an FM converter its defeating the purpose.
...and I'm going to wait until Sirius starts broadcasting, so i can get some opinions to compare the two, to see which one i want to subscribe to
crutchfield has CD head units that are satellite ready ranging from $200-$1000..plus you got to pay about $75 -$100 for the antenna.
here is a site the has some info on it
