Couldn't agree with you more.  The important point is that you can't insert 
an SWR meter or wattmeter in the line to make adjustments and then take it 
out.  The GE Z-match gives you the directional coupler which gives you a 
leg up on the adjustment process.  Otherwise you are stuck with the max 
output for min current.  Of course that should be our objective anyhow but 
many don't have an ammeter or voltmeter on the power source (I just 
replaced stuck plastic meters on one of my Astrons with digital panel 
meters: <http://astron.w4zt.com>).
