Otherwise, the latest variable-shade, auto-darkening lids from Optrel and ArcOne are what I'd recommend. I have an ArcOne IDF81 that I like well, even though its included headgear has the stops only on one side (which made it pretty faulty), so I modified/changed it out to a common Jackson 370 headgear that I like better than any other headgear, and the mod only costs about $15.
