the new alpine stuff is looking better... it seems they have un-gayed their decks again, offering some of the better bassengine features, and 4 volt preouts again.
i would definitely take a look at the reviews before i buy however.

what i might suggest is to buy a cheapie used deck for now, and wait until everyone releases their new 2007 stuff, then select from that.

even if nothing really appeals, the 2006 gear will start dropping in price soon.
