Gentlemen,
have a look at
http://www1.jaycar.com.au/productView.asp?ID=HP9530&CATID=&keywords=tank&SPECIAL=&form=KEYWORD&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATIDThis is a commercial product that I have used for years.
Although this is an Australian supplier the Tank would most likely be made
in China or one of those eastern countries.
The same tank can be bought from several suppliers in this country so I
would be surprised if it were not available in most countries in the world.
