I use an old Fibremetal Tigerhood 190 with the large glass (that I'm finding now they don't seem to make anymore except for the "Golden tiger which is a gold coated version of the same one), my dad bought it some 20 years ago and just hasn't abandoned his 40 year old helmet, I was given this one new in package when I learned how to weld and it still hangs over my bench at work. I'm not a full time welder but I've used auto-darks and hated them, still found myself flipping them up to set up work. I'll put up with having to do "the nod" to drop my hood for what welding I do.
About the most upgrading I plan on is putting a gold lense in it next time, supposed to make it easier for blue eyed folks to see.
