I got my CDD back from a local repair service this past Saturday. I took my CDD to Modulular Electronics in Roswell, GA after talking with Benny there about my situation. He said that he had a source for a CDM12 but I warned him that from what I had read on the web that Madrigal had modified it and that it would not simply swap in. I gave him the information from Pinvan and told him to have at it.
So Benny purchased a new CDM and discovered that the cd clamp is different. [I think that is what he said] Regardless, Benny took the laser assembly from the new module and moved it into my existing transport.
And voila, my CDD lives. The total repair cost was $275 (that's parts & labor)!
I asked Benny what he had to take apart to get the cd module out and it was way more involved that I imagined - it was basically a full disassembly of the unit. I'm glad that I aborted my attempts to get the CDM12 out of there.
