Wingnut,
I have a normal helmet, but a friend of mine just got one of the new automatic ones. Actually, he is on his 2nd one. He didn't like the first one as it was slow to clear up after the arc stopped. He said it is like having a 3rd hand and is the best thing in his 35 years of welding. Him, I trust on welding! I am pretty sure he has one that is adjustable for shade and I know he spent ~250.00.
Like you, I often use a 500W worklite, but it takes time to set it up, and they really heat you up! (Which ain't a bad thing this time of year /w3tcompact/icons/smile.gif.
