This unit is definitely worth the price, but remember, you get what you pay for in most cases. In this case it seems well built and has many features that I need. The only reason it's not a 5 Star rating is because the air pressure gauge doesn't seem to work. I adjusted the pressure in the back, but no reading from the front gauge. I regulated the pressure at the source and the plasma cutter worked just fine. I wouldn't use this for commercial fabrication, but it will do just fine on my diy projects.
