I was in the same boat about 2 weeks ago. I had the alpine 9827 and it got stolen. I was leaning towards the alpine 9851, but instead went back to the pioneer DEH-770 (premier). I have been through 2 pioneers and an alpine, and honestly as much as I try to convince myself I like the alpine...the pioneer is a better radio. Dont get me wrong, the alpine is a great deck...but dollar for dollar, the pioneer is the best. Hope this helps.
