Looking for some advice as I need a new car stereo head unit. I figure I may as well get some of the goodies I don't have now such as Ipod hookup and bluetooth. Not looking to spend over $200 and I was just wondering if there is any real difference between most of the choices at BB. You know, Alpine, Pioneer, Sony, JVC, Kenwood, etc. Or am I better off just picking the one I find easiest to operate?
