Miller Elite here , kickass helmet , lots of settings , has a grind mode on it as well , bad thing is you have to take the helmet off to set it but other then that it works great , i also love the fact you can adjust the sensitivity of the tint , i was welding out side and it would tint , i turned down the sensitivity so it would tint only when i stuck an arch . i have a ESAB as well and since buying the Miller it collects dust hangin on the wall . Optrel has a really helmet as well but it,s $600+ and cover lenses are alot more expensive and harder to find around here as well .
As much as I hate the chineese crap and giving money to china, I use the adjustable harbor freight one. I have tigged all day and never got the "itchy eye" so it must be working. I have two, one for mig and one for tig that stays clean of spatter. Can't beat the 60.00 price tag. Maybe someday a name brand one, but for now 60 bucks is 60 bucks.
I agree with JCRVETTE he stated exactly what I was going to say. I recently broke my helmet and went to northern tool and picked up their cheapest one. It works AMAZING! tig/mig doesn't matter. It's solar powered also so you don't have to turn it on/off or deal with batteries. I know that sounds petty but to me it's a hastle.
I have a Miller Performance Series, its my first auto-dark helmet. Its very light weight compared to my old fixed shade helmet. I like it overall, but it'll flash me once and while on the first weld of the day. Pisses me off. If I push the rest button before starting welding then it doesn't do it.
I used $450 miller helmets at work and I prefer my $100 hobart from tractor supply over them. Its solar powered and simple to use. Only issue I hate is the light sensors are only on the bottom of the shield so you can count on getting blinded a couple of times when welding in a cage.
Whatever you do make sure your helmet has sensors on top and bottom of the screen.
i have one of those harbor freight "specials" what a POS, doesn't stay up when you flip it, small viewing area, auto dark works marginally... just don't have the budget for a "good helmet", going to try the Clark at Menards next... about 50.00 auto dark, large (I think 4x5) viewing area, padded forehead pad we'll see i guess. Now if I could just learn to weld i'd be alright LOL
