HM Digital makes a decent PPM meter [TDS3] ..but a PPM meter isn't what
you want...they are designed to meter "salt water" and silver water isn't
salt water.
Looks like this one is on the low end of their line.
A PPM meter is useful for CS ...but not very.
Try an HM Digital EC3

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".
