I sold an extra VR-2 Mariner I had about a year ago for $300. It was in good, but original condition. I have no clue about the Dacor, many folks collect them but I have no experience with them. Have to agree with Herman that the Dacor is likely worth much less.
I've rebuilt my VR-1 (including rechroming] and VR-2 so they are fully diveable. Once you put on new hoses, mouthpiece, 2nd stage diaphragm, rechrome, duck bill or DBE, etc... the value is several hundred dollars higher. My 2psi.
Plus, I get an excuse to show off mine.
