Orbe Upgrade from AC/QC/PS to DC/NC/PS worth it?

I have a "2000" vintage Orbe with the AC motor and QC PS. The upgrade to the NEW DC motor with the NC (Never Connected) PS is $2000. Outside ofthe TNT review has anyone made/heard this upgrade? Is it worth it?
May I suggest you consider the Origin Live Ultra motor controller and dc motor as an alternative to the NC? I don't have any direct experience with the NC, but my OL Ultra was a spectacular upgrade on my Gyrodec! And at $1400, a bargain.
