DMR-HS2 spare parts? (Panasonic DMR HS2)

[qanda]This thread is about the Panasonic DMR HS2. Click here to see full specs[/qanda]My DMR-HS2 has stopped recognizing DVD-R discs. Another thread mentioned a flat-rate repair option, but that no longer exists. Does anybody know how much this might cost with the new service? They won’t quote over the phone even though it is pretty obvious drive replacement.

Better yet, is there a direct source for replacement drives for the HS2?

Please ignore this thread, and respond in the older thread:
