How much mechanical and simple wiring do you percieve yourself doing? Can you braze with a torch? 1 55 gallon barrel is free or cheap and a heating element new is 12 bucks and the fitting is 3. The cheap pump is 50 bucks or scrounge around and make mixing apparatus or use a homedepo paint mixing rod. Its all cheap, just get all of your chemicals coming so when your ready your ready. Magnesol, methanol, KOH, filters, so on and so forth.
