I have 3 $ 50 cheapies. I keep thinking I might do more welding and get a really good one. I don't like the battery powered one because I forget to turn it on. , sometimes when repairing Farm and construction equipment the auto dark doesn't work right because It doesn't see the start up arc. one of them I have to stick on a piece of duct tape because the dial turns as I move around. and I still have a couple old style with different shades.
