As far as a good head unit with many features, if you can get your hands on an Alpine CDA-7878, you can get the best of all worlds. MP3 playback, 4v preouts, digital time correction, built in 7 band parametric eq, all sorts of goodies. The Clarion H/U mentioned earlier will be damn near impossible to get a hold of because they had the first batch made and they severely under-estimated the cost of production, so they decided that they can't stay competitive in the market of MP3 playback units. If you like them, get them now if anyone like Crutchfield or a local car audio shop has any left. Personally. I ran the Nak cd40z for a while and switched to the Clarion dxz715 about a month ago. My Alpine 7878 is on order!
