Hell, if you wait long enough, you can pick up anything (new or used) cheap(er) (relatively speaking). Pioneer makes a sweet hard drivebased headunit, as does Sony. There have been multiple MP3 headunits on the market (RioCar being one that I have owned as well). I liked the RioCar, but I found it to have WAY too many options for my liking (or needing), so I felt more comfortable going back to a single-CD headunit. I may purchase the 6-disc changer someday, or may end up going to some more advanced media player... who knows, but I'm happy with what I bought so far!

By the way... I try to NEVER pay MSRP for anything. If I have to buy used, then I buy used or may refurbished. Usually you can find good deals on new equipment on the net if you look hard enough.
