I went to my local welding shop and they let me try a variety of helmets in their welding booth. I needed something with great visibility and ergonomics for a MIG/TIG stainless steel multi-position tube welding test, and chose the ESAB A60. It has a big viewing area, yellow tint which helps me see the puddle more clearly, really fast darkening, and I like the ability to change parameters for welding TIG, MIG, grinding, etc. I got it with the magnification lens which I like, too. And I don't notice it's there even after wearing it a long time. I've welded together two entire Jeep bodies with this helmet, along with some frame work, and it works flawlessly every time.
Moral Of The Story #1: If you intend on doing serious welding (anything on a vehicle, not just crafts) , get something comfortable with good visibility which suits your eyes.
Moral Of The Story #2: If your situation fits Moral #1, make sure you try some out before spending your money.
Moral Of The Story #3: Don't be afraid to spend a little money.
