You could get maybe get a second hand 1 off eBay, I see them advertised sometimes, Saffire 3, same as I have. You get the cutting attachment for them too.
I would recommend having a look for them on ebay. The murex ones are fine.
The small BOC torch is expensive, and spares aren't available, so if you accidentally bend the stem on the valve, like I did, the torch is scrap. A VERY expensive mistake. Unless someone on here knows different.
