Recommendation for a water distiller for making oil?

I thought that this topic must been covered here previously, but a search didn't find a recommendation of a specific distiller, or even much info at all regarding this method.

I found this video on youtube: , and thought that this looked like an inexpensive and simple way to make oil. Also, I need to make distilled water for my humidifier (at least a gallon a day), and being rather frugal cheap, I thought that using a water distiller to serve double duty seemed like an ideal solution.

So I'm hoping that someone here can share their experience, preferably with a specific model of distiller, but at least with the process of with making oil using water distillers, in general.
