Hand Held GC for Ethanol Testing

In the UC Davis Quality Control and Analysis for Winemaking class, I learned that there are several methods of measuring ethanol. There are combinations of distillation with hydrometry, pyncnometry, densitometry, or dichromate oxidation and titration, in addition to ebulliometry, near infrared, enzymatic, HPLC and GC methods. There was a table provided that listed the advantages and disadvantages of the various methods that I am reproducing here:

I was reading the newest edition (November-December 2011) of Vineyard and Winery Management and came across an ad for something called the Mini GC (gas chromatograph) for analyzing ethanol levels. The mini GC is about the size of a shoebox weighs about 3 pounds and comes with the Lab Navigator which can control, monitor and analyze the test results from the GC.
Has anyone tried this equipment?
