This is so cool. Absolutely gorgeous footage.
On the note of the Domesday Duplicator: I have a quite large collection of JP laserdiscs. Like, 300+. I'd love to back up and archive them in such quality, but it's a shame that no one is building Domesday Duplicators as a service. I'm familiar with soldering and moding, but the wiki suggests it's a bit beyond my expertise to build.
EDIT: Maybe I am wrong and you can now buy them assembled!
