I believe the Studio line (like the Ferre brand itself) is owned and produced by Ittierre S.p.a., the same company that (until recently) produced many of the diffusion lines in the industry from D&G to Versace jeans Couture to Extre, Malo, CNC Costume National, Just Cavalli, etc. They have licenses with Versace, Cavalli, and CN but actually own Ferre, Malo, and Exte.
That being said, if you look around you could probably find one quite reasonably. I often see them on sale at places like Off Saks. Retail would probably be in the range of D&G or slightly higher, perhaps $1100 or thereabouts.
