It looks like EC meters are much less expensive than what I had seen 
previously. One of the sites given to me earlier had a meter but it was well 
over $100. 

I hate to be a pain but would  a meter such as this one on ebay 
(http://tinyurl.com/yzzzvbn) be appropriate for these solutions?

  You can use a voltmeter to tell when to stop, but only on a given setup 
that's always the same as referenced by an EC meter.
Current, electrode spacing and surface exposure have to be constants for 
voltage to tell you anything.
  In *making* CS, the voltage is nearly irrelevant, so it needn't be a 
constant.

  A PPM meter is an EC meter that dilutes the info it gets to suit "salt 
water".
