My RCBS is pretty trouble free. My Lee 20 pounder dripped but I can live with that. I did learn not to leave my Lee full when done. It liked to get half melted then drain the bottom half of the pot onto my bench then finish melting. I just added ingots to the cold pot, turned it on, no more problems.
I do always keep a cast iron fry pan under the spout just for this type of mishap. Call it the voice of experience.
