I use a Lee 4-20 pot and like it. One thing I learned the hard way is that there is a weak link in the design that can cause a problem.
Users can avoid a potential problem by simply putting a smear of Anti Seize paste on the machine screw that adjusts the pour valve rod. I think this part is an off the shelf 8-32 cabinet pull attaching screw and not of industrial strength. Mine stripped after several casting sessions and I had to drill it out and retap it to 10-32.
It's fine now, but it was a lot of bother, I guess that was Leementing.
