Sirius car kit?

I have the same one that ktulu has (Sportster). Love it.
The boom box is great. Just like ktulu, I had major issues with the antenna and had to use the one for my indoor stereo base station.

A bud of mine has the one you are looking at. I think I like it better, if that helps you any.
He doesn't have the boom box, so I don't know about it.
