Years ago I had a Lee Production Pot. It worked great even with my first 6 cavity Lee mold but it drained the pot fast.
I then got a old beat up Saeco 20 lb bottom pot with an old Hensley and Gibbs 6 cavity mold. They both stayed with me for a few years.
I replaced it with a Lyman 20lb one that I got on a 'gun' trade. I still use it. About once a year I need to replace the cord. The contacts 'burn out' at the pot.
