I still have my original Zerostat (the body of which is glossy red, both smaller and more rounded than the Zerostat III) sitting in a drawer, but stopped using it when in the 1980’s I got the already-mentioned Nagaoka Kilavolt No. 103, which I greatly preferred. If you find a used one, snap it up!
Another great anti-static gun is the Furutech Destat III, which unfortunately sells for around $300. If you’re patient, you may get lucky and find one for $200, as did I on an auction site.
Whichever pistol you use, de-stat both sides of your LP whilst holding it in your free hand, off the table’s platter.
