+1 for the Optrel helmets ^^^ top quality
I left mine in the basement for 3+ years, did some TIG and it still worked like new. Had it for 10 years and didn't even know there was a battery?? Keep in mind the clear lens front on these helmets. Some are specific to the manufacturer or helmet so find out how much replacements are. Some employers might squak about special ordering them, or they can be high speed polished which is what i do...
I'd lend you mine Greg but its 3.5 hours away
Ive used the same Lincoln helmet (different paint job) youre looking at too for many hours and dont really have any major complaints, it was kind of the beater to throw aound when i did special effects
This but might be worth a look for $99.
