Grabbed a CDX off ebay for $150. Unit came with 1 3 button, 1 6 button, and the official power adapter. Sadly, no A/V cable, and I have a model 1 genny, so I can't test it yet as the one I ordered didn't show up yet.
But, it powers on fine, and the overall shape is very good. Other than some green marker on the underside it doesn't have a single scratch on it, and only 1 tiny scuff mark near the line out jack.
