I also use one for my iPod. I think it's OK, mine is about $70. You can find some cheaper. The price does not affect the sound quality I guess. The quality is like the radio, no stereo most of the time. if you really want iPod like quality, you should install the audio system with the USB input. I asked and it costs around $1600 at MK. That's why I think $70 is good enough!
