I have used a Durastill Model 3040 in a "Stan" country before. These worked great. We had three of them for about 45 people.
The only thing with an manufactured distiller. You MUST plan for any Filters. Most have Inline water filters or some kind. Also if your in a hard water area you WILL have build up on internal pipes. Plan for your cleaning too and repair parts if your going overseas with no mailbox.
Home stills are fun!!
