I just bought myself a nice Hobart welder this weekend an a Metal Man helmet fro Northern Tool.
The Metal Man helmet was right next to the Lincoln helmets and looked identical.. Same packaging and everything.. It was a $10 difference in price. It has a adjustment on the side of it that allows you to select the shade of darkness 9-13 and a grind mode, that you can select and it will stay clear so. I'm happy with it!
