My first ADF was a Hunstman Nitro (about $120.00 all over the place) It has shade 9-13, light weight, and a super-comfotable headgear. It has NEVER failed so far, even under low-amp TIG. My main helmet is a Speedglas 9100x that I got a great deal on, but, after welding with it, if it went out, I'd gladly pony up the $400.00 or so that they currently go for, rather than go back to the Nitro. Once you use a High-end helmet, just the peace of mind that you have a unit that will NOT fail is worth it, along with a bigger viewing area, and superior clarity in light state, so you can see where you're going next without lifting the helmet. Bottom line, again my opinion, Huntsman Nitro, $120, great low end tig, comfortable, small viewing area. Speedglas 9100x, $400+, great EVERYWHERE, more comfy that the Nitro, large viewing area. Northern tool special, $60.00, don't risk your eyes on it.
