o what is considered an inexpensive micron / thermistor vacuum gage?
After a quick search most of these gages run between $200 to $450.
These would appear to be gages for daily professional use. I found
one gage for $137


I got the Robinaire model you cited for $97 from Network Tool Warehouse
-- http://www.ntxtools.com . They frequently have really hot deals on
refrigeration equipment. Apparently, they buy new stuff from factories,
but also do large buys from distress sales, and offer the materials at
pretty spectacular prices.
