I have the opportunity to buy a high end Pioneer HU from my cousin for $100 even. He's the second owner, and it will just be the HU and faceplate. No manual, no remote, no box, just what's needed to play music. I couldn't tell you the cosmetics of it. I bet it's fairly worn. However, I don't know if it's the 7600 or the 6600 version.
What do you think?
