Pure water & Stills

[Penn]

There is a major pure water source initiative thats been developing (http://www.pgwi.org/)
I'm thinking about one of these:http://www.milehidistilling.com/
as I do not want to build a still, not for single Jersey Malts, but for steady small scale safe water production. The web has an endless source products, I'm thinking portable, low P/M, has anyone here possess first hand knowledge with operating a still. Photos would be a good thing here.
