   I have been a strong advocate for the 53131/2 counter since I first
   encountered in in 1993. Most of my applications are for a time-interval
   counter (TIC) measuring the time interval between an atomic clock and
   GPS (see my Timing for VLBI papers at [1]http://gpstime.com). The two
   reasons are
    1. It is simple and cheap and reliable, especially for the casual
       user.
    2. It has a simple RS-232 "printer" interface that is really easy to
       use. Rick Hambly used the 53131/2 simple interface to make his
       Tac32Plus (and Multi) software packages into an integrated TIC
       logging utility (see
       [2]http://[3]cnssys.com/cnsclock/Tac32PlusSoftware.html)

   If you are shopping for a counter, try to find a 53132. It has an extra
   digit at the 100 psec level that is quite useful. They appear on Ebay
   quite often. My last purchase was a 132 at the $1k level.
   73, Tom
