I have the new bolt buster 2. It's not a torch, but it has a place. It's real nice for loosening lock-tite, working around plastic and wiring harnesses, inside interiors, etc.
Well worth the money. It doesnt replace a torch all the time, but if you dont have a torch or would rather not use one this item is the ticket. It's faster to use/set up as well.
It'd pay to shop around for the best price on these. They can be had for around 300-350$. The Mini ductor brand is also decent, but I prefer the bolt buster after having used both.
