scale? budget?
if you need less than 5 gal, you should go with a glass reflux still from a chem glass supplier. I’m sure @Sidco_Cat could point you at one.
if you’re playing with 100’s of gallons, go with an off theshelf beverage unit with a long bubble column with a defleg on it.
In between? I’m using a 26gal conical fermenter with hot water running through the jacket as my recovery still at the moment. I’ve got a 2"x 8’ reflux column I can put on there if I wanted to use it to refine my recovered ethanol (which I might start doing. thanks @Soxhlet).
That same still head will fit on any sanke beer keg (15 or 7.5 gal. smaller available). heat double boiler or bane-marie style.
