If you have a tape deck, I highly recommend going that route. FM transmitters , IMO, have horrible sound, and are extremely overpriced. I haven't had luck with one yet. I got a phillips tape adapter from CVS for 10 bucks, and it works great. I think Monster makes one if you want to go for a good brand. I've been told it doesn't make a difference, but I've heard some crappy ones. I can vouch for the Phillips. If you can avoid FM transmitters, I would, like the plague.
