I happen to own a Henrob, and thank goodness I only paid $10.00 for it at an auction, because I don't think it is worth a whole lot more than that.
I have a Smiths aircraft torch for the lighter work. ( it's just lighter and handier for sheet metal and thin wall tubing ) It is also handy if you are going to be welding for any period of time. It is amazing how heavy a torch can seem to be after a few hours.
For the heavier cutting, I have a larger Victor torch that I bought almost 40 years ago. I never need to use it for welding because I like the smaller torch. For most of my welding nowadays, I use a wire feed, except when I have to hammer or work the welded metal.
The Henrob has an advantage if a person is cutting sheet metal, because the heating flame is directed in one spot rather than a rosebud like a standard cutting torch. This cutting process requires that you have enough room to be able to turn the torch in the direction you want to cut (not always possible). Another feature of the Henrob that I personally don' like is that the pistol handle puts your hand close to the work, so you have to have that large bulky shield in front of your hand to protect it.
As far as I am concerned, the only feature on the Henrob that would make it worth having one, if it was a bargain, is the ability to cut without spreading too much heat. For everything else, any quality torch is just as good. I am only giving my personal experience here, so if there are people who have better ways of using these torches, I would be happy to hear them.
