[hpsdr] Can Mercury be purchased any more? If so where?

[David Kirkby]

I was looking at this project with interest and see that Mercury:

http://openhpsdr.org/mercury.php

is described as "Perhaps the most exciting of all the modules, the
Mercury module that enables direct sampling of the 0-65 MHz spectrum
..."

only to find that the module is not available from TAPR.

http://www.tapr.org/kits_merc.html

being marked as "Sorry, this item is no longer available"

Is there a good reason this is not available from TAPR? Is it
available from anyone else? Does anyone know what the approximate cost
fo the module was when it was available?
