Depends on what you want to do with the tool and what tools you already have. I wasn't familiar with this tool so I did a search on the internet. It looks like an improved oxy/acetelyne torch. By the time you buy the regulators and tanks, you will have around $1000 in the setup. If you are going to do a lot of sheet metal or thin wall tubing work, it will probably work well for you. If you are going to do general bodywork and some thicker material welding, I would think a good MIG welder would be a better choice.
