I have the DEH-P5500MP, its really more of a middle of the line model, but it has tons of adjustments and does everything I need it to do. I like the way it looks too, I had the 5300 and it was stolen and this is the replacement model. I take my face off now when I park it. The only thing I don't like about mine is the way the buttons are on it you have to press them lightly or they don't work, but i think thats normal for it you just have to get used to it. I've always bought Alpine in the past and loved them, and I haven't had a Pioneer long enough to judge the quality of it, but my friends have had good luck with Pioneer and it was considerably cheaper than a comperable Alpine so I went with it, I think it cost $250. It has a nice remote control too, not
as good as the one Alpine uses, but its pretty good. Hopefully, I won't have to deal with their customer service.
