I purchased the the the blank iron tank from brownells and it seems to to the job just fine. I also purchased the corresponding tank lid. It comes with the weather stripping applied to the back of the lid to seal in the goodness while in production. After 4 cookings I removed the weather stripping as it started to fail. I now place a piece of tin foil over the tank and then place the lid over that to help stop evaporation in between down times. I figure why skimp. I built my own tank stand and brackets to hold the pipe heater that I also bought from Brownells. The pipe heater was way over priced and I have since secured the dimensions and will build the next one myself for about 40.00 and a few drill bits. If you wish i can post pictures of the stand. which cost about 50.00 to build and turned out really nice.
