Topic pretty much says it all. What is the most inexpensive mp3 playing head unit that will work with Lucid's DCI?

 

I'm not up on head units, but when I was looking (2 years ago) the Sony's were cheapest. I think the factory store I was in recently still had some of the original MP450 (refurbs) for around $179. It has the hard-wired jack too, so you have a choice of using the wired DCI (just for Sony but easier install) or the infra-red one.
