Hi Anthony, I was very interested in your comments as I don't have either system yet. I like the bit about Serius offering more weather and I know they have more sports, which I don't care about, but I believe XM has more bigband and traditional jazz, which is my primary interest. XM offers a 30's 40's and 50's channel that plays the stuff I really like. How does Serius compare to this? Can anyone give me a comparison? Thanks much. Kris Hickerson --
