I'm on my first pioneer, a Premier DEH 980BT. 8-9 months, zero problems. The onlly complaints I have are some userfriendliness issues as compared to my Alpine, but the thing is packed with SQ and tuning features and has given me no problems. For Alpine, I would go with something from the older line when they used to put features in their head units. I have no interest whatsoever though in anything below the 9886. The other big names offer at least a few feature-rich head units to choose from, for Alpine serious SQ fans have the 9887 or else 9886/9884+ more money for IMPRINT.
Let's see... my 980 has 16 band EQ, time alignment, built-in bluetooth, 5 volt low resistance outputs, subwoofer phase control, just to name a few things. I know there are some awesome older Alpines but name anything in their line currently made below the 9887 that has ANY of that.
Last couple Alpines I had I started having error messages when trying to read my IPOD.
I have given up on Alpine and am liking Pioneers and Eclipses right now.
