I've been using a Lee Pro 4 20 pound bottom pour pot for over a decade now and it's getting old. I've cleaned it out and rebuilt it a couple of times now, and it works for awhile, but then slowly returns to its driptastic bad habits. I think it's time I start saving up my coin for a new pot. What are your recommendations for the most reliable, and least drippy bottom pour pots? These could be modern ones that are off the shelf, or vintage models that Grandpa bought back when they invented electricity. What are your thoughts?
