a decent bottom pour lead furnace with 25 lb capacity currently advertised for $260-$310
a turkey frier, a cast iron pot with a 50 lb capacity and a dipper lists for under $100 if you shop carefully
it heats faster and has twice the capacity, and yes its not ideal, but it does work and does not require you work near an electrical outlet
so working on a screened porch or open garage doorway is a decent option and allows you to get good ventilation so your not breathing lead fumes
