I've got an older 3M Speedglas 9000x that I'm still using. It's been a terrific helmet with the exception of the headgear design. (It likes to rip the hair right out of your head.) It cost me close to 400 bucks
years ago, so it's going to get used until
it dies or
I do....
Unfortunately auto-dark helmets are like computers. No matter which one you buy today, it will surely be discontinued and out of date a couple years from now.
