I just barely got a Sony CDX-MP70 and I love it! ( I was a sucker for the different colored backgrounds to choose from and the turn knobs style. You know, when a good song comes on it's much better to have a knob rather then a button! lol)MP3 decks are great especially when it comes to 175+ track CD's! But I have had Kenwood Excelon series decks in the past and really liked them, but I tried Sony this time. IMO Kenwood Excelon decks, Sony or even Pioneer have always been great decks and car audio gear.
