I didn't list any rules, what I said is common sense, don't put dirty ingots and that applies to all. The mod with the plunger is very easy to do and it fixed the problem for me. I see no reason to spend $365 vs $65 when Lee works. I spend money on PID controller, I would spend extra money if I could increase capacity to 40lb but no such option. So what if I get occasional drip, I just put ingot mold or small cast iron pot underneath and it's all good. Can't justify spending $300 extra with no real benefit. I also took Lee Magnum melter ($33 what it cost me for new one) and replaced the pot with bigger stainless steel pot from thrift store ($3) and insulated with ceramic blanket which is covered with aluminum sheet metal. It doesn't have bottom pour but increased capacity about 30lb let's me melt a good batch of alloy. Next step, I got even bigger container I picked up, will put 2 of the Lee heating elements 700 + 700 = 1400 watt, drill the bottom and install bottom pour system similar to lee and than add simple system to hold the pot which will be also insulated with ceramic blanket. Not paying $600, the technology in the pot is not complicated, will be controlled with same PID controller.
