Well you could always go old school, and make a working still from stainless stock pots, and easy to get plumbing parts.
If you can solder, and cut a hole in stainless, you can build a 10 gallon stock pot still for around a hundred bucks.
For a continuous feed system it gets about 50 bucks more expensive but exponentially more dangerous. The temptation to walk away, and do something
else is too great, and accidents happen.
Here's a pict of what I am talking about. If you run a recirculating liebig and use Expanded teflon foam as a gasket, you can recover around a 2GPH
of pure DI.
I'd recommend using a carbon filter to clean the water Before distilling, and a second one in the Vapor path.
I wasn't thinking when I replied the first time. My fingers type while I chase monkeys in my mind...
