Best pre-amp of the three: Copland CT-305, BATVK-31SE. or PS Audio's PCA-2 ??

I am again retooling  my system back to separates. I would like some feedback and comments about the above three pre-amp from present or former owner ,or anyone. Obviously all are on sale USED on Audiogon  and the ads for each are running out of time.  In their order of expense: THE Copland's  is the most expensive, ....next, BAT VK-31se, and  the PS Audio PCA-2 (which is under $1000)

. 

 ******CORRECTION:  The BAT was selling on e-bay; The auction has expired, but the seller claims he will relist.      Thank you
