I知 just getting started into casting and am now ready to buy a furnace. I知 looking at either the Lyman Mag 20 or the RCBS Pro-Melt. The RCBS furnace is around 80 bucks higher. Which of the two would you folks recommend or would you suggest another brand. I知 not crazy about buying a Lee after reading about the spout problems. I would like a 20 lb furnace.
