We're going to get dd a satellite radio for her car for X-mas. Can anyone who has one give me some recommendations on which one. She mentioned XM Radio, and on their website it says a portable one should be coming out in late November. Not sure though, which one to get her. I don't mind spending $3-400.00 on one, I just want to get her a good one, complete with everything that she would need. I don't want to ask her which one she's interested in as I want it to be a surprise. Any help would be appreciated. TIA
