I was looking at new auto dimming helmets in Bunnings yesterday Vlad. Mine is a little worse for wear.
Cheapest one that I saw was $39 - wouldn't buy one like this. But most of what they had on the shelf there were around the $100 mark - I'll probably end up with one of these.
I'd like a "top end" one, but can't really justify the cost for the amount of time I'll use it.
The "window" on my current one is about the 98 x 44 size you've mentioned. It's slightly larger than my old standard flip window style, and I've always found it to be large enough. Mind you, I have to wear reading glasses behind the helmet and get in pretty close to the work to be able to see what I'm doing anyway.
