Looks Chinese, that's bad. Oxy-Gasoline torches have been around for quite some time. Their primary use has always been demolition. If you're looking to get a very nice torch outfit, I love my torch from www.smithequipment.com. I bought it through www.weldingsupply.com. It is a medium duty cutting and welding outfit. I have seen the best deals on ebay, <$200 for everything you need to get started but cylinders. If you're going to be working on automotive, I suggest you get the light duty setup. I have welded as thin as 22 guage, but it is tricky with the larger medium duty tips.
To answer your question, No, I havent tried this. I would stay with the Smith, or Victor brands they are tried and true. You can get parts for them most anywhere. For body work the lite duty is great, for hevyer (frame,thick brackets) medium duty is OK.
Just my opinion with, lets just say, over 30 years use of both these brands.
I guess it depends on what you plan on using a torch for, but since I got a plasma arc a few years back, haven't touched my torch. Yeah, the cost a bunch more, but it works so much better on frames and other metal fabrication IMO it is well worth the extra expense.
Bought a Smith many years ago, but now have a Plasma cutter. Wouldn't trade it for anything.
Torches don't work well for cutting sheet metal, if that is what you planned to do, buy a plasma cutter.
I have used one of those torches. They do work rather nicly. The tip is a two piece system that has a different seat than the rest.
I wouldn't buy one as, where do you purchase parts for it. Dependibility in the long run I wouldn't know. I only used it at a demo. Never on a job sight!!!
As for cutting sheetmetal with a torch. turn the heat down low. have the ox at 20 psi instead of 40 psi. point your torch at a 70' to the work. Try that. I know a plasma cutter works a whole lot better, If you dont have one use what you have.

...use a small tip, like a OO {double ott}.... Did I spell that right??? bill
Yes you could use a 00 for instance. with the tip turned at an angle the material would burn away with not loosing the kurf.
Try it on a 1/8" piece forst then move down to .030 I am not going to say it is easy. I have done it several times. It doesn't always come out how I would like it to. I mainly use a plasma cutter for small thin material but when you do not have the plasma you use what you have. Now tring to cut a perfect shape will not work with this process. you still need to grind and feather the material. If you turn the oxy to an oxyidising flame you can do the same but have more control. It all takes practace
