You have to make sure it's PIONEER PREMIER, not some rip off that's trying to copy it. The best thing is the warranty, my Pioneer Premier DEH-P960MP had several issues that I got fixed over that 2 yr. period. It also had 6.5v preouts when the Standard Pioneer version has only 4v. I would buy Pioneers Premiere line over the standard line just because of the warranty alone, and it usually only costs about $15 difference.
