It is getting to the point that this question is going to be irrelevant in a few years. With the way car makers are integrating everything with the sound system, aftermarket head units are going to be a thing of the past pretty soon. And, that is very disappointing! Currently, in my 1991 Honda Accord, I am using an old school Eclipse CD8051. This is one very cool head unit. I, also, own a 55040, CD8454, and a CD8053. But, I really like the CD8051, so I will just keep an eye out for other NOS CD8051, CD8052, CD8061, or CD8062 units (these are all pretty much the same unit).
