BAT VK80 or REX II?

Question on the newer BAT preamps and phono stages, VK-80, VK-P80 and VK-90, VK-P90 have been seeing them at some real good prices, does anyone know what is going on as they seem like pretty new items? Does BAT have replacements for these items? 

I agree with @dentdog but he meant to say you should contact Geoff Poor at Glenn Poor's Audio-Video in Champaign, IL.  He is the guy you need to talk to without a doubt. He knows BAT and Dunlavy.

Yea, got it backwards. Victor loves his power supplies which are thought highly of and the REX units have the separate PS.
