I have always used JVC arsenal line for my head unit, they ever failed me. Nice looking, decent sound quality, only thing people don't like is the USB is kind slower then the alpine and kenwood eXcelon, the sound quality are a little better on the iPods and radio. Pioneer Primer is another good one sound quality are very legit, for the price you can't go wrong either. My own personal would choice Pioneer Primer over JVC arsenal, Alpine are good for the speed of the iPod connection, but your paying more then what your paying on the Arsenal, they pretty much the same, all about personal experience.
