Thiis was a great read. I've continuously wondered if my old Zerostats were still working. I got the first one probably in 1970 and 2 more since then. I've also had reasonable results with the Walker Audio Talisman I remember a tiny spark on the first one, I also have a felt mat that I also zap (off the TT) such that it does not cling to the vinyl. For me it's the tried and true method - obviously along with clean record and stylus.
Found a Milty Zerostat alternative
I was thinking about buying the Milty Zerostat but came across a discussion regarding this plasma arc lighter.

It really works well! I took a record out of it's sleeve and held a tissue against it. The tissue stuck to it, even when held upside down. I turned on the plasma lighter and held it about 1.5" away and made two or three circular passes around. Tried the tissue test again and it would not stick to the vinyl. It's also well constructed and doesn't feel cheap.
