Check Ebay often, because they pop up from time to time. Trouble is, there's a LOT of other people looking for the same head units and the bidding tends to get a little outrageous. Here's the section you'd find them in:

There's also a site that allows you to search the parts inventory at a lot of salvage yards, nationwide, for specific parts. I've found several of the CD/cassette units on here too:

I was trying to find one too, so I could replace the standard cassette one in our '93 whose tape player crapped out, but I ended up not. Never drove the car enough to ever want anything more than just basic radio, which still works great.
