I've had speedglas since the 90's. speedglas is by far the best on the market. I just retired my 9002 model with adflo unit after 10 years of daily use, and it's still very usable with a new battery. There are much cheaper brands out there but, key word CHEAP. If you call yourself a welder, spend the money. You wont be disappointed. Get the XXi lens, its like watching 4K movies.
