Neuros II. I have the original Neuros and an very happy with it. If you want more info, look at the online forums at that website. There's an excellent community there that even the CEO of the company, Joe Born, is active in. The company is also in the process of trying to get the firmware to be open source (open.neurosaudio.com). The downside is that the player is rather large, but there is a mini-player due out during the summer.
If you already have one, then I think Belkin makes an FM transmitter. I've never used it, though.
