Hi, I am a fairly happy XM subscriber. I love O&A, hate Stern, and love XM's alt rock channels. However the music I listen to the most is classic rock and hard rock, even a little hair metal when I am in a cheesy mood. I find XM's offerings in these areas too schizophrenic or too obscure. Some friends have suggested I might be better served by Sirius in this regard if I can put up with short playlists (I think I can, my tastes in this area aren't particularly sophisticated). Anyway what is the cheapest reciever I can get for my car? I also would rather pay a little more then have to put up with mail in rebates I always forget to send in. I see circuit city has the Xact Plug n Play on sale for 40 bucks. Would I be reasonably happy with this unit. I am more then happy with my Roady 2 which I connect to a line in input on my car stereo. Other than trying to make it all look neat on my cluttered dash are there any issues from connecting both recievers at the same time? Any advice on recievers or whether subscribing to both services might be right for me would be appreciated.
