Found an old thread over at CP about the Sanctum Arts stuff with this comment directly from Sanctum Arts:
"I would like to confirm that SA RDL7 lines are discontinued products. It was announced over at another forum eight months ago that some of the products will not be coming back onto the market. Sorry and thank you..."
Too bad too. From what Im seeing around there was a lot of other great stuff in that line. The only remnanats appear to be that big hologram room which apparently got sold to Daz as a P/C item.  I wonder if maybe the artist that made them left Sanctum Arts.
