Will the tank seal if laid on its side?  Presumably you won't be using the tank standing up.  Round tanks tend to waste a lot of space compared to a rectangular or square tank.  I have no idea if the cost is good or not as I have never priced out a stainless tank.

It would have to be standing up. Yes there is wasted space, but Im sure I could pack small things around it....

  Any water tank of sufficient size would have to be necessarily thick enough to be structuraly sound, and it would then be quite heavy. With scrap copper at $4 pound, sheet copper has to be mind numbing expensive.

  Cheapest is a poly tank, best is without question stainless. It would certainly be much, much cheaper than copper, and its basically sanitary simply by being stainless.

  Copper plumbing is okay, if it wernt the stuff would be banned and its not. The problem was with older homes, they used soldered copper lines, and the solder was lead based. I really doubt anyone became retarded over it, but all solder used in plumbing today is required to be lead free.

  I just bought a plastic welder, and plan to make my own custom poly tanks. Looks pretty simple. You can cement bungs into the tank that are pipe thread, and could attach copper line from there. But again, you could buy a lot of pex and PVC for what you'll spend on copper tubing. I would only use copper where I was looking for heat gain or loss. Solar heat collector, or cooling evaporator
