If you were going to buy a new satellite radio, which one would it be?  In the case that you already have one, or have experience with them, which is yuor favorite?

If I was going to pick an XM radio, it's have to be this one, the XpressRC. 

On Sirius, I'd pick the Sportster 5.  I like that it's portable and dockable, so I can either have it in a static place on my car, or take it with me. 

Which is your favorite, and why?
