Cheaper... better... these are relative, I would always say try your ideas at least once on a small scale, the best way to do anything is the way that is right for you. I like to use a $29.00 HotPot to melt mine with, then pour the lead into 1 and 2 lb ingots for production, I have tried several ways but this works for me. I have used a fish fryer that runs off a tank for a gas grill, melted the lead in a basic cast iron pot, worked great for a long time. The HotPot is nice, holds about 4 lbs and has a nice open top on it for scraping off the slag and melts the medium very quickly once its warmed up, but always try new ideas, at least half of our "hairbrained" schemes work out one way or the other, JIM
