Welders - Is the Cobra/Henrob/DHC Torch any good?

I have wanted to get into welding for a while. Was browsing tools on CL ran across and ad for a Cobra Torch (apparently the same as a DHC or Henrob).
Looks very interesting - cuts similar to a plasma and welds just about anything but titanium. Due to the multiple functionality it would save a ton of $$$ on start up cost for fabrication.

For those of you that have seen these in real life or actually owned or used one - is it as good as advertised? Can you give some pros and cons about the rig?

For those that arent familiar with it - here are a couple links:

I would not try to weld most stuff with a torch like that. Especially anything thin. I would invest in a good 220V MIG and then either a set of oxy-fuel torches or plasma cutter. I find that my oxy-fuel torches have a ton of other uses besides cutting. Don't skimp on the brand of welder. Save up some money and buy a good used Miller or Lincoln. The off brands are cheaper for a reason...

That's a pretty slick kit with the handgrip/etc. I've never done any welding with Oxy/Acet, although I have a PortaTorch setup for heating/cutting. MIG welding is a breeze, and for a hobbyist like me, the Hobart 140 has been fantastic. Obviously if you want to weld aluminum and titanium you'd need to go up a model or two. I've always wondered what the difficulty level is with Oxy/Acet welding.

I do a bunch of TIG welding. Oxy-Act welding is very similar, but a lot more heat is transferred. One of the biggest things to worry about with using a torch to weld with on a vehicle is catching everything else on fire. Its fine if your welding bare steel on a bench. But, for example, welding sliders on a Jeep is not going to end well....

Here is a set I just welded onto a KJ. I own my own fab shop.

How about for building stuff like bumpers off the vehicle? It says that it will weld up to 3/8 and that is far more that I would ever need for anything I would be attaching to my CJ.

A couple things make this set up interesting for me - one is the start up cost. To have ability to cut similar to a plasma, lay down a weld similar to a Tig and weld aluminum for a start up cost of $395 plus gas and regulators is intriguing to say the least. I cant imagine getting started with a Tig machine, cutting device (gas or plasma) and needed accessories for less than 2.5K. With the Cobra/DHC there is no electrical supply to worry about either which could possibly be and additional expense for those of us weekend warriors that don't have our own shop. Another thing that interest me about this method is that is appears to be easy to learn. I've tried stick welding and I can truly say I never really got the hang of it. I can braze my arse off and this method, while different, seems to have a lot of similar characteristics.

My main concern would be that this rig does not work as advertised. If someone has actually used this method I would be interested to hear your take on it. I wont be sinking any $$$ in anytime soon but I must say - if this outfit works as billed it might ba a viable start up rig. If it doesnt I wouldnt care to waste my $$$.

All that is is a pistol grip cutting torch with brazing tips included.

To get the penetration you'd need for anything structural you would end up getting the surrounding metal way too hot. There's a reason why electricity is used for welding and heat and time are the main reasons.

That thing is full of snake oil.

Yeah - that makes a lot of sense. I like the way that thing cuts but I was a little more skeptical of the welds. I think when its time to buy I'll look around for one of the smaller MIG set ups - either a Miller, Lincoln or Hobart 140 or 180 to start off with and learn.
