I concur on the "el cheapo".
My arc welder came with a non-darkening helmet. I was a total novice as to welding at the time, and had problems getting welds started with that helmet,, bought an auto darkening one for around $50 on Ebay and saw the quality of my work improve dramatically.
That said, about 7 or 8 years later my el cheapo may be starting to crap out on me now,, I only use it a few times/year but it seems like now I have to extract/reinstall batteries to get it to turn on, and also it seems to get too dark when it darkens, makes it hard to see well what's going on... But I would throw this one away & buy another $50 one before I would spend a lot on a high dollar one. Now, if I used it every day (or even every week) I might buy a nicer, more expensive one. I consider the cheap helmet a consumable like the welding sticks at this point.
