I bought a water still sterilizer conversion, off Amazon, with adjustable temperature, from 80C - 108C, for 170$C It collects the alcohol back, so I only lose what I can’t get back out of the weed. Which is about a quarter to half of a liter per run of a100 grams of weed.
I am now working on getting more out with a G clamp and a couple of pieces of wood strapping, to squeeze out as much as I can.
