Pioneer Premier or Alpine. Nothing else. You can get a high end Alpine or Pioneer for a good price (~$200) online - Why waste money on lesser decks like Panasonic or JVC? I have owned 3 high end Pioneer decks (8200, 9300, 9400) and I currently own an alpine 9833 and I love it. All were excellent head units. I have yet to experience the full potential of the Alpine deck, however, because I am still running the craptastic Sony speakers the previous owner installed.
