I have a Harbor Freight auto-darkening welding helmet and the only issue I have is that the headband will let loose on occasion. I ordered a box of 3 replacement headbands and still have two of them left. So I'm probably good for the rest of my life.
There is one other issue. I sometimes forget to swap from my grinding face shield to my welding helmet. One strike of the arc is a reminder to change them.
Some have a grinding feature that keeps the lens clear when grinding, which would be nice. I bet you could get one of those for your $150 budget.
