Without calling and bitching if you want all channels it's $199 a year. Why would someone get a select package for $165 a year? For $34 more you get the full package.
After a year of the package you call and bitch and they give you a reduced rate from the $199.
The other thing not that it's overly important but to some it is, you don't get Stern on the select package on the XM side of things.
The better deal is to go lifetime. If something happens to your receiver or you get a new one, you can transfer your package. There's a charge for it but if you are buying a new receiver it's worth it.
If you are looking for a good deal try this on for size... it's a better price than you'll pay through SIRI and you get the car dock as well....
