Roadrunner reapearance

I saw on the latest edition of Analog Planet on MF’s video of the show he attended that at the SOTA booth, they had a working product of the Roadrunner w/motor/pulley as a drop in for a VPI. Anyone here have more info or even better, have one in use? It was reported it is now a product for sale @ $1k. No mention of it on SOTA’s website.
