[The Goober]

I tried the monster cable (I think) one in my car and couldn't get it to not sound like crap. People seem to have very mixed experiences with these, even in the same city. I think a lot depends on the setup of your radio and how well it recieves signals from within the cabin (mine sounded better if I could get the transmitter up on my dash by the windshield, but that wasn't a good place to leave it). Either way, if you drive any sort of distance you are doomed to have to keep adjusting the channel as you pass through different areas.

If you have a tape deck, a simple tape adapter thingy sounds better and requires less screwing around. Whenever I get another car (used likely) I hope it has a tape deck and not a CD player for this reason.
