Just a quick update - Jeff sent me an email about a project he and Pete Hand are collaborating on.  It is a new four letter word machine.  Pete's design (below) is being tweaked and mass produced by Jeff and should be for sale in the near future.  The blank PCBs have been delivered and have been sent off to have the surface mount components added.  The device with 4x tubes and a power adapter is estimated to cost $499.  This new design will also support a GPS time reference and that option will cost $549.  A machined polycarbonate enclosure will be released eventually.  (Sorry, no photos at the moment.)
