I have two of the Superfire torches, (one in use and the other still unused as a spare).
I would advise you look at a complete Rothenberger kit which will be a tote bag, SF2 torch, gas bottle, plus other Roth tools including pipe slice. (Various kits available)
Works out much cheaper. Think I got a kit for over £60, which when you consider the cost of the Roth grips, slice, gas bottle, tote bag and SF torch, it means you get the torch for a bargain price.
I also have a Monument torch which I haven’t soldered with yet. It has a very good flame, but feels a bit lightweight made
