Thanks Sounddesigner, yes part of my reason for asking about the Scope reverbs is that I have never felt they were fabulous 
but given the power of Scope cards and S-C Excite this is where Really Good reverbs 

 could live , given that I am mixing more 
inside native systems Cubase / StudioOne4 these days but their big reverbs still consume too much of the native processing imo , 
therefore an External FX bussed to Scope setup works really well .  
I'm thinking , in general terms , just as the way that there is no such thing as a bad microphone , the same could be said for 
Scope Reverbs ... and the more the better 
  
The UrsaMajor Spacstation looks interesting .
