I would suggest a long-time brand if planning to keep it. I purchased the Hypertherm 65 from my local welding supply store and have been very pleased with performance; but this month they will no longer manufacture this unit per website. What does that mean, not sure. It says the will continue to supply consumables. Maybe it is just the model # being discontinued? Guess time will tell.
My miller tig and mig units haven't given me one issue(6 years now). I guess in some cases you get what you pay for. Buy once and be happy with it.
