I'm looking at getting a Pioneer myself. The displays are really nice on em. Plus lots of other good features. You might also wanna look at the Premier line, little bit better specs.
I've used Alpines in the past and I like them, but every Alpine product I have ever purchased has broke. The display on my last one only worked half the time after about 2 1/2 yrs. That unit replaced one that had a dead cd player after about 4 yrs. I also had a Alpine amp that died within a year, however it was replaced in warranty with another that lasted me another 6 yrs. I also originally had a Alpine six disc changer but it died after a couple years, had to rip it apart to get my discs back

I still think they make nice stuff but can't say much for its lifespan.
Anyway thats my thoughts, I havent listened to the Pioneer yet just internet browsing right now.
