Personally I like to see people build their own stills , but these things are a bloody good deal, I reckon it cost me that or more to build mine using all new materials . Needle valves , sight glasses, triclamps, copper pipe in 4 inch , 2 inch, 3/4 inch, 1/2 inch, 4 inch and 2 inch reducers, solder , flux, mapp gas just to name a few.......it all adds up.
Anyone thinking about building would probably be better of jumping on one of these. im almost tempted myself.
