Hi Pete!

        I think Ham Radio carries them for about $1000.  Before
spending that, you might consider their software version called
World Watch which lists for $50.  http://www.geochronusa.com/

        Depending on what you want to do, there are better
software programs available IMHO.  I use one called DX-Aid 
which costs $25...see some plots here:
